After over 20 years as a Software Engineer, Architect, and Manager, I want to pass along some unsolicited advice to junior developers either because I grew through it, or I've had to deal with developers who behaved poorly:
1) Your ego will hurt you FAR more than your junior coding skills. Nobody expects you to be the best early in your career, so don't act like you are.
2) Working independently is a must. It's okay to ask questions, but ask sparingly. Remember, mid and senior level guys need to focus just as much as you do, so before interrupting them, exhaust your resources (Google, Stack Overflow, books, etc..)
3) Working code != good code. You are an author. Write your code so that it can be read. Accept criticism that may seem trivial such as renaming a variable or method. If someone is suggesting it, it's because they didn't know what it did without further investigation.
4) Ask for peer reviews and LISTEN to the critique. Even after 20+ years, I send my code to more junior developers and often get good corrections sent back. (remember the ego thing from tip #1?) Even if they have no critiques for me, sometimes they will see a technique I used and learn from that. Peer reviews are win-win-win.
5) When in doubt, do NOT BS your way out. Refer to someone who knows, or offer to get back to them. Often times, persons other than engineers will take what you said as gospel. If that later turns out to be wrong, a bunch of people will have to get involved to clean up the expectations.
6) Slow down in order to speed up. Always start a task by thinking about the very high level use cases, then slowly work through your logic to achieve that. Rushing to complete, even for senior engineers, usually means less-than-ideal code that somebody will have to maintain.
7) Write documentation, always! Even if your company doesn't take documentation seriously, other engineers will remember how well documented your code is, and they will appreciate you for it/think of you next time that sweet job opens up.
8) Good code is important, but good impressions are better. I have code that is the most embarrassing crap ever still in production to this day. People don't think of me as "that shitty developer who wrote that ugly ass code that one time a decade ago," They think of me as "that developer who was fun to work with and busted his ass." Because of that, I've never been unemployed for more than a day. It's critical to have a good network and good references.
9) Don't shy away from the unknown. It's easy to hope somebody else picks up that task that you don't understand, but you wont learn it if they do. The daunting, unknown tasks are the most rewarding to complete (and trust me, other devs will notice.)
10) Learning is up to you. I can't tell you the number of engineers I passed on hiring because their answer to what they know about PHP7 was: "Nothing. I haven't learned it yet because my current company is still using PHP5." This is YOUR craft. It's not up to your employer to keep you relevant in the job market, it's up to YOU. You don't always need to be a pro at the latest and greatest, but at least read the changelog. Stay abreast of current technology, security threats, etc...
These are just a few quick tips from my experience. Others may chime in with theirs, and some may dispute mine. I wish you all fruitful careers!221 -
They call it $5/gb hotel wifi, i call it free uncapped 100meg fibre because your security sucks
Oh and they host their entire POS (and database with backups) on the same network accessible to every TV in the hotel

Hacking/attack experiences...
I'm, for obvious reasons, only going to talk about the attacks I went through and the *legal* ones I did 😅 😜
Let's first get some things clear/funny facts:
I've been doing offensive security since I was 14-15. Defensive since the age of 16-17. I'm getting close to 23 now, for the record.
First system ever hacked (metasploit exploit): Windows XP.
(To be clear, at home through a pentesting environment, all legal)
Easiest system ever hacked: Windows XP yet again.
Time it took me to crack/hack into today's OS's (remote + local exploits, don't remember which ones I used by the way):
Windows: XP - five seconds (damn, those metasploit exploits are powerful)
Windows Vista: Few minutes.
Windows 7: Few minutes.
Windows 10: Few minutes.
OSX (in general): 1 Hour (finding a good exploit took some time, got to root level easily aftewards. No, I do not remember how/what exactly, it's years and years ago)
Linux (Ubuntu): A month approx. Ended up using a Java applet through Firefox when that was still a thing. Literally had to click it manually xD
Linux: (RHEL based systems): Still not exploited, SELinux is powerful, motherfucker.
Keep in mind that I had a great pentesting setup back then 😊. I don't have nor do that anymore since I love defensive security more nowadays and simply don't have the time anymore.
Dealing with attacks and getting hacked.
Keep in mind that I manage around 20 servers (including vps's and dedi's) so I get the usual amount of ssh brute force attacks (thanks for keeping me safe, CSF!) which is about 40-50K every hour. Those ip's automatically get blocked after three failed attempts within 5 minutes. No root login allowed + rsa key login with freaking strong passwords/passphrases.
linu.xxx/much-security.nl - All kinds of attacks, application attacks, brute force, DDoS sometimes but that is also mostly mitigated at provider level, to name a few. So, except for my own tests and a few ddos's on both those domains, nothing really threatening. (as in, nothing seems to have fucked anything up yet)
How did I discover that two of my servers were hacked through brute forcers while no brute force protection was in place yet? installed a barebones ubuntu server onto both. They only come with system-default applications. Tried installing Nginx next day, port 80 was already in use. I always run 'pidof apache2' to make sure it isn't running and thought I'd run that for fun while I knew I didn't install it and it didn't come with the distro. It was actually running. Checked the auth logs and saw succesful root logins - fuck me - reinstalled the servers and installed Fail2Ban. It bans any ip address which had three failed ssh logins within 5 minutes:
Enabled Fail2Ban -> checked iptables (iptables -L) literally two seconds later: 100+ banned ip addresses - holy fuck, no wonder I got hacked!
One other kind/type of attack I get regularly but if it doesn't get much worse, I'll deal with that :)
Dealing with different kinds of attacks:
Web app attacks: extensively testing everything for security vulns before releasing it into the open.
Network attacks: Nginx rate limiting/CSF rate limiting against SYN DDoS attacks for example.
System attacks: Anti brute force software (Fail2Ban or CSF), anti rootkit software, AppArmor or (which I prefer) SELinux which actually catches quite some web app attacks as well and REGULARLY UPDATING THE SERVERS/SOFTWARE.
So yah, hereby :P39 -
Another story on the spirit of wk93. TL;DR I DOS'd the whole campus network for some beers.
In highschool teachers had this blackboard system (a sort of moodle) and we used to have really lazy teachers who only read the PowerPoint presentations and made us take notes. One day I was fed up with their bullshit and figured these lazy ass professors wouldn't "teach" crap as soon as there was no internet connection...so the race was on...
10 minutes before the bell rang a friend and I managed to break in into a computer lab, I booted up Kali and searched for the access points, 3 routers through the building all with CISCO OS.
I figured they had all the default configs, time was running out so I decided to Smurf the three access points with the lab's IP range, scheduled an automatic shutdown in 2 hours and blocked the PC. The bell rang and as predicted, no internet, no class, my friends and I used that free time to go to a bar (on a Monday afternoon).
Funny side note, since the 3 routers were down the whole network collapsed, no cameras, no access control, no faculty network or any network. We kept doing it and every time we did campus security would be desperately searching for someone with a black hoodie.

Navy story time, and this one is lengthy.
As a Lieutenant Jr. I served for a year on a large (>100m) ship, with the duties of assistant navigation officer, and of course, unofficial computer guy. When I first entered the ship (carrying my trusty laptop), I had to wait for 2 hours at the officer's wardroom... where I noticed an ethernet plug. After 15 minutes of waiting, I got bored. Like, really bored. What on TCP/IP could possibly go wrong?
So, scanning the network it is. Besides the usual security holes I came to expect in ""military secure networks"" (Windows XP SP2 unpatched and Windows 2003 Servers, also unpatched) I came along a variety of interesting computers with interesting things... that I cannot name. The aggressive scan also crashed the SMB service on the server causing no end of cute reactions, until I restarted it remotely.
But me and my big mouth... I actually talked about it with the ship's CO and the electronics officer, and promptly got the unofficial duty of computer guy, aka helldesk, technical support and I-try-to-explain-you-that-it-is-impossible-given-my-resources guy. I seriously think that this was their punishment for me messing around. At one time I received a call, that a certain PC was disconnected. I repeatedly told them to look if the ethernet cable was on. "Yes, of course it's on, I am not an idiot." (yea, right)
So I went to that room, 4 decks down and 3 sections aft. Just to push in the half-popped out ethernet jack. I would swear it was on purpose, but reality showed me I was wrong, oh so dead wrong.
For the full year of my commission, I kept pestering the CO to assign me with an assistant to teach them, and to give approval for some serious upgrades, patching and documenting. No good.
I set up some little things to get them interested, like some NMEA relays and installed navigation software on certain computers, re-enabled the server's webmail and patched the server itself, tried to clean the malware (aka. Sisyphus' rock), and tried to enforce a security policy. I also tried to convince the CO to install a document management system, to his utter horror and refusal (he was the hard copy type, as were most officers in the ship). I gave up on almost all besides the assistant thing, because I knew that once I left, everything would go to the high-entropy status of carrying papers around, but the CO kept telling me that would be unnecessary.
"You'll always be our man, you'll fix it (sic)".
What could go wrong?
I got my transfer with 1 week's notice. Panic struck. The CO was... well, he was less shocked than I expected, but still shocked (I learned later that he knew beforehand, but decided not to tell anybody anything). So came the most rediculous request of all:
To put down, within 1 A4 sheet, and in simple instructions, the things one had to do in order to fulfil the duties of the computer guy.
I. SHIT. YOU. NOT.
My answer:
"What I can do is write: 'Please read the following:', followed by the list of books one must read in order to get some introductory understanding of network and server management, with most accompanying skills."
I was so glad I got out of that hellhole.6 -
This is kind of a horror story, with a happing ending. It contains a lot of gore images, and some porn. Very long story.
TL;DR Network upgrade
Once upon a time, there were two companies HA and HP, both owned by HC. Many years went by and the two companies worked along side each one another, but sometimes there were trouble, because they weren't sure who was supposed to bill the client for projects HA and HP had worked on together.
At HA there was an IT guy, an imbecile of such. He's very slow at doing his job, doesn't exactly understand what he's doing, nor security principles.
The IT guy at HA also did some IT work for HP from time to time when needed. But he was not in charge of the infrastructure for HP, that was the jobb for one developer who didn't really know what he was doing either.
Whenever a new server was set up at HP, the developer tried many solutions, until he landed on one, but he never removed the other tested solutions, and the config is scattered all around. And no documentation!!
Same goes with network, when something new was added, the old was never removed or reconfigured to something else.
One dark winter, a knight arrived at HP. He had many skills. Networking, server management, development, design and generally a fucking awesome viking.
This genius would often try to cleanse the network and servers, and begged his boss to let him buy new equipment to replace the old, to no prevail.
Whenever he would look in the server room, he would get shivers down his back.
(Image: https://i.bratteng.xyz/Ie9x3YC33C.j...)
One and a half year later, the powerful owners in HA, HP and HC decided it was finally time to merge HA and HP together to HS. The knight thought this was his moment, he should ask CEO if he could be in charge of migrating the network, and do a complete overhault so they could get 1Gb interwebz speeds.
The knight had to come up with a plan and some price estimates, as the IT guy also would do this.
The IT guy proposed his solution, a Sonicwall gateway to 22 000 NOK, and using a 3rd party company to manage it for 3000 NOK/month.
"This is absurd", said the knight to the CEO and CXO, "I can come up with a better solution that is a complete upgrade. And it will be super easy to manage."
The CEO and CXO gave the knight a thumbs up. The race was on. We're moving in 2 months, I got to have the equipment by then, so I need a plan by the end of the week.
He roamed the wide internet, looked at many solutions, and ended up with going for Ubiquiti's Unifi series. Cheap, reliable and pretty nice to look at.
The CXO had mentioned the WiFi at HA was pretty bad, as there was WLAN for each meeting room, and one for the desks, so the phone would constantly jump between networks.
So the knight ended up with this solution:
2x Unifi Securtiy Gateway Pro 4
2x Unifi 48port
1x Unifi 10G 16port
5x Unifi AP-AC-Lite
12x pairs of 10G unifi fibre modules
All with a price tag around the one Sonicwall for 22 000 NOK, not including patch cables, POE injectors and fibre cables.
The knight presented this to the CXO, whom is not very fond of the IT guy, and the CXO thought this was a great solution.
But the IT guy had to have a say at this too, so he was sent the solution and had 2 weeks to dispute the soltion.
Time went by, CXO started to get tired of the waiting, so he called in a meeting with the knight and the IT guy, this was the IT guys chance to dispute the solution.
All he had to say was he was familiar with the Sonicwall solution, and having a 3rd party company managing it is great.
He was given another 2 weeks to dispute the solution, yet nothing happened.
The CXO gave the thumbs up, and the knight orders the equipment.
At this time, the knight asks the IT guy for access to the server room at HA, and a key (which would take 2 months to get sorted, because IT guys is a slow imbecile)
The horrors, Oh the horrors, the knight had never seen anything like this before.

What are all these for, why is there a fan ductaped to on of the servers.
WHAT IS THIS!
Why are there cables tied in a knot.
WHY!
These are questions we never will know the answers too.
The knight needs access to the servers, and sonicwall to see how this is configured.
After 1.5 month he gains access to the sonicwall and one of the xserve.
What the knight discovers baffles him.
All ports are open, sonicwall is basically in bridge mode and handing out public IPs to every device connected to it.
No VLANs, everything, just open...10 -
A conversation with our network/system admin.
Me : Can I install linux on my computer, windows is slow and terrible.
Him : No, if you use anything but Windows in this company, you will be fired for bypassing our security protocols. Its written in your contract.
Me : *boots up my Macbook*

So the new mass surveillance law will be going into effect from the 1st of January.
Of course, since I'm very keen on my security/privacy, I'm going to implement some precautions.
- A few vps's connecting to tor, i2p and VPN provider so that I can always use a secure connection.
- Setup anti tracker/ads/etc etc shit on the VPS's. Probably through DnsMasq and the hosts file.
- Use Tor browser by default. I've tried this for a while now and damn, the tor network has become way faster than only even a year ago! Some pages literally only take a few seconds to load.
- Wipe my laptop, encrypt the harddrive and at least put QubesOS on it together with probably a few other systems.
- Ungoogle my new phone, use it with VPN by default.
- Get rid of all non encrypted communication services. I think that only leaves me with a few account removals because I haven't chatted unencrypted for nearly a fucking year now.
If anyone has any more ideas, please share!42 -
So I had my exams recently and I thought I'd post some of the most hacky shit I've done there over here. One thing to keep in mind, I'm a backender so I always have to hack my way around frontend!
- Had a user level authentication library which fucked up for some reason so I literally made an array with all pages and user levels allowed so I pretty much had a hardcoded user level authentication feature/function. Hey, it worked!
- CSS. Gave every page a hight of 110 percent because that made sure that you couldn't see part of the white background under the 'background' picture. Used !important about everywhere but it worked :P.
- Completey forgot (stress, time pressure etc) to make the user ID's auto incremented. 'Fixed' that by randomly generating a user id and really hoping during every registration that that user ID did not exist in the database already. Was dirty as fuck but hey it worked!
- My 'client' insisted on using Windows server.Although I wouldn't even mind using it for once, I'd never worked with it before so that would have been fucked for me. Next to that fact, you could hear swearing from about everyone who had to use Windows server in that room, even the die hard windows users rather had linux servers. So, I just told a lot of stuff about security, stability etc and actually making half of all that shit up and my client was like 'good idea, let's go for linux server then!'. Saved myself there big time.
- CHMOD'd everything 777. It just worked that way and I was in too much time pressure to spend time on that!
- Had to use VMWare instead of VirtulBox which always fucks up for me and this time it did again. Windows 10 enjoyed corrupting the virtual network adapters after every reboot of my host so I had to re-create the whole adapter about 20 times again (and removing it again) in order to get it to work. Even the administrator had no fucking clue why that was happening.
- Used project_1.0.zip etc for version control :P.
Yup, fun times!6 -
Navy story continued.
And continuing from the arp poisoning and boredom, I started scanning the network...
So I found plenty of WinXP computers, even some Win2k servers (I shit you not, the year was 201X) I decided to play around with merasploit a bit. I mean, this had to be a secure net, right?
Like hell it was.
Among the select douchebags I arp poisoned was a senior officer that had a VERY high idea for himself, and also believed he was tech-savvy. Now that, is a combination that is the red cloth for assholes like me. But I had to be more careful, as news of the network outage leaked, and rumours of "that guy" went amok, but because the whole sysadmin thing was on the shoulders of one guy, none could track it to me in explicit way. Not that i cared, actually, when I am pissed I act with all the subtleness of an atom bomb on steroids.
So, after some scanning and arp poisoning (changing the source MAC address this time) I said...
"Let's try this common exploit, it supposedly shouldn't work, there have been notifications about it, I've read them." Oh boy, was I in for a treat. 12 meterpreter sessions. FUCKING 12. The academy's online printer had no authentication, so I took the liberty of printing a few pages of ASCII jolly rogers (cute stuff, I know, but I was still in ITSec puberty) and decided to fuck around with the other PCs. One thing I found out is that some professors' PCs had the extreme password of 1234. Serious security, that was. Had I known earlier, I could have skipped a TON of pointless memorising...
Anyway, I was running amok the entire network, the sysad never had a chance on that, and he seemed preoccupied with EVERYTHING ELSE besides monitoring the net, like fixing (replacing) the keyboard for the commander's secretary, so...
BTW, most PCs had antivirus, but SO out of date that I didn't even need to encode the payload or do any other trick. An LDAP server was open, and the hashed admin password was the name of his wife. Go figure.
I looked at a WinXP laptop with a weird name, and fired my trusty ms08_067 on it. Passowrd: "aaw". I seriously thought that Ophcrack was broken, but I confirmed it. WTF? I started looking into the files... nothing too suspicious... wait a min, this guy is supposed to work, why his browser is showing porn?
Looking at the ""Deleted"" files (hah!) I fount a TON of documents with "SECRET" in them. Curious...
Decided to download everything, like the asshole I am, and restart his PC, AND to leave him with another desktop wallpaper and a text message. Thinking that he took the hint, I told the sysadmin about the vulnerable PCs and went to class...
In the middle of the class (I think it was anti-air warfare or anti-submarine warfare) the sysad burst through the door shouting "Stop it, that's the second-in-command's PC!".
Stunned silence. Even the professor (who was an officer). God, that was awkward. So, to make things MORE awkward (like the asshole I am) I burned every document to a DVD and the next day I took the sysad and went to the second-in-command of the academy.
Surprisingly he took the whole thing in quite the easygoing fashion. I half-expected court martial or at least a good yelling, but no. Anyway, after our conversation I cornered the sysad and barraged him with some tons of security holes, needed upgrades and settings etc. I still don't know if he managed to patch everything (I left him a detailed report) because, as I've written before, budget constraints in the military are the stuff of nightmares. Still, after that, oddly, most people wouldn't even talk to me.
God, that was a nice period of my life, not having to pretend to be interested about sports and TV shows. It would be almost like a story from highschool (if our highschool had such things as a network back then - yes, I am old).
Your stories?8 -
Today my roomate told me about his classmate who asked a really nice question " why do we need a MAC address in a WINDOWS machine". They are in a masters course for network security.9
-
It was fun to watch my entire high school (~1200 people) freak out when I ran "net send * Big brother is watching you..." on what I found to be an insecure computer in my high school's library. Every single computer in the building displayed the pop up message. The town's IT director even showed up to figure out what happened.
I was caught, but they were more happy it wasn't a hacker, and that I discovered that the IT firm the town hired totally botched properly implementing network security, so I was let off the hook.5 -
Well, here's the OS rant I promised. Also apologies for no blog posts the past few weeks, working on one but I want to have all the information correct and time isn't my best friend right now :/
Anyways, let's talk about operating systems. They serve a purpose which is the goal which the user has.
So, as everyone says (or, loads of people), every system is good for a purpose and you can't call the mainstream systems shit because they all have their use.
Last part is true (that they all have their use) but defining a good system is up to an individual. So, a system which I'd be able to call good, had at least the following 'features':
- it gives the user freedom. If someone just wants to use it for emailing and webbrowsing, fair enough. If someone wants to produce music on it, fair enough. If someone wants to rebuild the entire system to suit their needs, fair enough. If someone wants to check the source code to see what's actually running on their hardware, fair enough. It should be up to the user to decide what they want to/can do and not up to the maker of that system.
- it tries it's best to keep the security/privacy of its users protected. Meaning, by default, no calling home, no integrating users within mass surveillance programs and no unnecessary data collection.
- Open. Especially in an age of mass surveillance, it's very important that one has the option to check the underlying code for vulnerabilities/backdoors. Can everyone do that, nope. But that doesn't mean that the option shouldn't be there because it's also about transparency so you don't HAVE to trust a software vendor on their blue eyes.
- stability. A system should be stable enough for home users to use. For people who like to tweak around? Also, but tweaking *can* lead to instability and crashes, that's not the systems' responsibility.
Especially the security and privacy AND open parts are why I wouldn't ever voluntarily (if my job would depend on it, sure, I kinda need money to stay alive so I'll take that) use windows or macos. Sure, apple seems to care about user privacy way more than other vendors but as long as nobody can verify that through source code, no offense, I won't believe a thing they say about that because no one can technically verify it anyways.
Some people have told me that Linux is hard to use for new/(highly) a-technical people but looking at my own family and friends who adapted fast as hell and don't want to go back to windows now (and mac, for that matter), I highly doubt that. Sure, they'll have to learn something new. But that was also the case when they started to use any other system for the first time. Possibly try a different distro if one doesn't fit?
Problems - sometimes hard to solve on Linux, no doubt about that. But, at least its open. Meaning that someone can dive in as deep as possible/necessary to solve the problem. That's something which is very difficult with closed systems.
The best example in this case for me (don't remember how I did it by the way) was when I mounted a network drive at boot on windows and Linux (two systems using the same webDav drive). I changed the authentication and both systems weren't in for booting anymore. Hours of searching how to unfuck this on windows - I ended up reinstalling it because I just couldn't find a solution.
On linux, i found some article quite quickly telling to remove the entry for the webdav thingy from fstab. Booted into a root recovery shell, chrooted to the harddrive, removed the entry in fstab and rebooted. BAM. Everything worked again.
So yeah, that's my view on this, I guess ;P31 -
So, continuing the story, in reverse order, on the warship and its domain setup...
One day, the CO told me that we needed to set up a proper "network". Until now, the "network" was just an old Telcom switch, and an online HDD. No DHCP, no nothing. The computers dropped to the default 169.254.0.0/16 link local block of addresses, the HDD was open to all, cute stuff. I do some research and present to him a few options. To start things off, and to show them that a proper setup is better and more functional, I set up a linux server on one old PC.
The CO is reluctant to approve of the money needed (as I have written before, budget constraints in the military is the stuff of nightmares, people there expect proper setups with two toothpicks and a rubber band). So, I employ the very principles I learned from the holy book Bastard Operator From Hell: terrorizing with intimidating-looking things. I show him the linux server, green letters over black font, ngrep -x running (it spooks many people to be shown that). After some techno-babble I got approval for a proper rack server and new PCs. Then came the hard part: convincing him to ditch the old Telcom switch in favour of a new CISCO Catalyst one.
Three hours of non-stop barrage. Long papers of NATO specifications on security standards. Subliminal threats on security compromises. God, I never knew I would have to stoop so low. How little did I know that after that...
Came the horrors of user support.
Moral of the story: an old greek saying says "even a saint needs terrorizing". Keep that in mind.4 -
I recently found a company that used employee social security numbers as their login username and their MMDDYYYY as their password (which could not be changed) also their entire network was using a router with no wifi password set. :/8

I wonder why banks are always so terribly insecure, given how much money there's for grabs in there for hackers.
Just a while ago I got a new prepaid credit card from bpost, our local postal service that for some reason also does banking. The reason for that being that - thank you 'Murica! - a lot of websites out there don't accept anything but credit cards and PayPal. Because who in their right mind wouldn't use credit cards, right?! As it turns out, it's pretty much every European I've spoken to so far.
That aside, I got that card, all fine and dandy, it's part of the Mastercard network so at least I can get my purchases from those shitty American sites that don't accept anything else now. Looked into the manual of it because bpost's FAQ isn't very clear about what my login data for their online customer area now actually is. Not that their instruction manual was either.
I noticed in that manual that apparently the PIN code can't be changed (for "security reasons", totally not the alternative that probably they didn't want to implement it), and that requesting a forgotten PIN code can be done with as little as calling them up, and they'll then send the password - not a reset form, the password itself! IN THE FUCKING MAIL.
Because that's apparently how financial institutions manage their passwords. The fact that they know your password means that they're storing it in plain text, probably in a database with all the card numbers and CVC's next to it. Wouldn't that be a treasure trove for cybercriminals, I wonder? But YOU the customer can't change your password, because obviously YOU wouldn't be able to maintain a secure password, yet THEY are obviously the ones with all the security and should be the ones to take out of YOUR hands the responsibility to maintain YOUR OWN password.
Banking logic. I fucking love it.
As for their database.. I reckon that that's probably written in COBOL too. Because why wouldn't you.23 -
Sooooo me and the lead dev got placed in the wrong job classification at work.
Without sounding too mean, we are placed under the same descriptor and pay scale reserved for secretaries, janitors and the people that do maintenance at work(we work for a college as developers) whilst our cowormer who manages the cms got the correct classification.
The manager went apeshit because the guidelines state that:
Making software products
Administration of dbs
Server maintenance and troubleshooting
Security (network)
And a lot of shit is covered on the exemption list and it is things that we do by a wide fucking margin. The classification would technically prohibit us from developing software and the whole it dptmnt went apeshit over it since he(lead developer) refuses (rightfully so) to touch anything and do basically nothing other than generate reports.
Its a fun situation. While we both got a substantial raise in salary(go figure) we also got demoted at the same time.
There is a department in IT which deals with the databases for other major applications, their title is "programmers" yet for some reason me and the lead end up writing all the sql code that they ever need. They make waaaaay more money than me and the lead do, even in the correct classification.
Resolution: manager is working with the head of the department to correct this blasphemy WHILE asking for a higher pay than even the "programmers"
I love this woman. She has balls man. When the president of the school paraded around the office asking for an update on a high priority app she said that I am being gracious enough to work on it even though i am not supposed to. The fucking prick asked if i could speed it up to where she said that most of my work I do it on my off time, which by law is now something that I cannot do for the school and that she does not expect any of her devs to do jack shit unless shit gets fixed quick. With the correct pay.
Naturally, the president did not like such predicament and thus urged the HR department(which is globally hated now since they fucked up everyone's classification) to fix it.
Dunno if I will get above the pay that she requested. But seeing that royal ammount of LADY BALLS really means something to me. Which is why i would not trade that woman for a job at any of my dream workplaces.
Meanwhile, the level of stress placed my 12 years of service diabetic lead dev at the hospital. Fuck the hr department for real, fuck the vps of the school that fucked this up royally and fuck people in this city in general. I really care for my team, and the lead dev is one of my best friends and a good developer, this shit will not fucking go unnoticed and the HR department is now in low priority level for the software that we build for them
Still. I am amazed to have a manager that actually looks out for us instead of putting a nice face for the pricks that screwed us over.
I have been working since I was 16, went through the Army, am 27 now and it is the first time that I have seen such manager.
She can't read this, but she knows how much I appreciate her.3 -
The stupid stories of how I was able to break my schools network just to get better internet, as well as more ridiculous fun. XD
1st year:
It was my freshman year in college. The internet sucked really, really, really badly! Too many people were clearly using it. I had to find another way to remedy this. Upon some further research through Google I found out that one can in fact turn their computer into a router. Now what’s interesting about this network is that it only works with computers by downloading the necessary software that this network provides for you. Some weird software that actually looks through your computer and makes sure it’s ok to be added to the network. Unfortunately, routers can’t download and install that software, thus no internet… but a PC that can be changed into a router itself is a different story. I found that I can download the software check the PC and then turn on my Router feature. Viola, personal fast internet connected directly into the wall. No more sharing a single shitty router!
2nd year:
This was about the year when bitcoin mining was becoming a thing, and everyone was in on it. My shitty computer couldn’t possibly pull off mining for bitcoins. I needed something faster. How I found out that I could use my schools servers was merely an accident.
I had been installing the software on every possible PC I owned, but alas all my PC’s were just not fast enough. I decided to try it on the RDS server. It worked; the command window was pumping out coins! What I came to find out was that the RDS server had 36 cores. This thing was a beast! And it made sense that it could actually pull off mining for bitcoins. A couple nights later I signed in remotely to the RDS server. I created a macro that would continuously move my mouse around in the Remote desktop screen to keep my session alive at all times, and then I’d start my bitcoin mining operation. The following morning I wake up and my session was gone. How sad I thought. I quickly try to remote back in to see what I had collected. “Error, could not connect”. Weird… this usually never happens, maybe I did the remoting wrong. I went to my schools website to do some research on my remoting problem. It was down. In fact, everything was down… I come to find out that I had accidentally shut down the schools network because of my mining operation. I wasn’t found out, but I haven’t done any mining since then.
3rd year:
As an engineering student I found out that all engineering students get access to the school’s VPN. Cool, it is technically used to get around some wonky issues with remoting into the RDS servers. What I come to find out, after messing around with it frequently, is that I can actually use the VPN against the screwed up security on the network. Remember, how I told you that a program has to be downloaded and then one can be accepted into the network? Well, I was able to bypass all of that, simply by using the school’s VPN against itself… How dense does one have to be to not have patched that one?
4th year:
It was another programming day, and I needed access to my phones memory. Using some specially made apps I could easily connect to my phone from my computer and continue my work. But what I found out was that I could in fact travel around in the network. I discovered that I can, in fact, access my phone through the network from anywhere. What resulted was the discovery that the network scales the entirety of the school. I discovered that if I left my phone down in the engineering building and then went north to the biology building, I could still continue to access it. This seems like a very fatal flaw. My idea is to hook up a webcam to a robot and remotely controlling it from the RDS servers and having this little robot go to my classes for me.
What crazy shit have you done at your University?9 -
Worst thing you've seen another dev do? So many things. Here is one...
Lead web developer had in the root of their web application config.txt (ex. http://OurPublicSite/config.txt) that contained passwords because they felt the web.config was not secure enough. Any/all applications off of the root could access the file to retrieve their credentials (sql server logins, network share passwords, etc)
When I pointed out the security flaw, the developer accused me of 'hacking' the site.
I get called into the vice-president's office which he was 'deeply concerned' about my ethical behavior and if we needed to make any personnel adjustments (grown-up speak for "Do I need to fire you over this?")
Me:"I didn't hack anything. You can navigate directly to the text file using any browser."
Dev: "Directory browsing is denied on the root folder, so you hacked something to get there."
Me: "No, I knew the name of the file so I was able to access it just like any other file."
Dev: "That is only because you have admin permissions. Normal people wouldn't have access"
Me: "I could access it from my home computer"
Dev:"BECAUSE YOU HAVE ADMIN PERMISSIONS!"
Me: "On my personal laptop where I never had to login?"
VP: "What? You mean ...no....please tell me I heard that wrong."
Dev: "No..no...its secure....no one can access that file."
<click..click>
VP: "Hmmm...I can see the system administration password right here. This is unacceptable."
Dev: "Only because your an admin too."
VP: "I'll head home over lunch and try this out on my laptop...oh wait...I left it on...I can remote into it from here"
<click..click..click..click>
VP: "OMG...there it is. That account has access to everything."
<in an almost panic>
Dev: "Only because it's you...you are an admin...that's what I'm trying to say."
Me: "That is not how our public web site works."
VP: "Thank you, but Adam and I need to discuss the next course of action. You two may go."
<Adam is her boss>
Not even 5 minutes later a company wide email was sent from Adam..
"I would like to thank <Dev> for finding and fixing the security flaw that was exposed on our site. She did a great job in securing our customer data and a great asset to our team. If you see <Dev> in the hallway, be sure to give her a big thank you!"
The "fix"? She moved the text file from the root to the bin directory, where technically, the file was no longer publicly visible.
That 'pattern' was used heavily until she was promoted to upper management and the younger webdev bucks (and does) felt storing admin-level passwords was unethical and found more secure ways to authenticate.5 -
I was talking in class. Teacher saw me. She asked me to explain the topic she was going to explain. It was Network Security. I started explaining how we can prevent tracking of our online activities by using VPN and all.
Teacher (to class): Do you all know about VPN?
Whole Class: No.
Teacher (to me): They don't know about VPN. Now, how will you explain?
Me: I won't.

So...
I'm penetrationtesting a network and the servers on said network
The network administrator and IT security officer knows this, because they hired me..
TL;DR a scan caused the network to crash.
Today I received a very angry email going "Stop scanning NOW!" from one of the IT departments.
Apparently I crashed their login server and thus their entire network...
It happened d the first time I scanned the network from the outside and they had spend an entire day figuring out how and repairing the service they thought was the problem, but then it crashed again, when I scanned from within the network.
Now they want to send me a list of IP's that I'm not allowed to scan and want to know exactly what and when I'm scanning...
How crap can they be at their job, if they weren't able to spot a scan... The only reason they found out it was me was because the NA had whitelistet my IP, so that I could scan in peace...5 -
So this shit happened today...
We were asked to implement a functionality on the device that allows it to go to standby mode to save battery power. Once the device enters that state, it can only be woken up by actual bus-network activity, and usually that means connecting a shit-ton of wiring harness and network emulation devices... Before implementing and releasing the device software that does this, we told that fucktard customer how difficult it would be for him to connect to the device without such a setup. He seemed to be fine with it and said rather arrogantly that we should implement the requirement as asked...
Well okay you cock-sucking motherfucker, you'll get exactly what you asked for... We implement the functionality and deliver the software...
Now this pile of shit comes back running his mouth on how the device tears down all its interfaces (to reduce power consumption) and he can't connect to the device anymore.... Well what else were you expecting you dickhead.
To make things worse for me apparently he runs to the manager describing his apparent problem. Both of them come to my desk.. With that fucking Bastard hiding his smugly mug behind the manager's back... He thought he was going to have the upper hand... Well guess what fucked piece of shit, I came prepared... I showed the manager how this was a part of the requirements by throwing that JIRA ID in their faces... The manager seems to understand but this relentless fuck wanted me to implement a "workaround" that would allow him to connect to the device easily... The manager almost had me implement that workaround, when I expose a huge security flaw in doing so. Guess what, now the entire team comes to my desk and start supporting my statement... To make it better they also tell how doing so will violate other requirements...
I've never felt so happy in my entire fucking career, when the entire team stood by me and watched that asshole drag his sorry ass back to his place5 -
Got laid off on Friday because of a workforce reduction. When I was in the office with my boss, someone went into my cubicle and confiscated my laptop. My badge was immediately revoked as was my access to network resources such as email and file storage. I then had to pack up my cubicle, which filled up the entire bed of my pickup truck, with a chaperone from Human Resources looking suspiciously over my shoulder the whole time. They promised to get me a thumb drive of my personal data. This all happens before the Holidays are over. I feel like I was speed-raped by the Flash and am only just now starting to feel less sick to the stomach. I wanted to stay with this company for the long haul, but I guess in the software engineering world, there is no such thing as job security and things are constantly shifting. Anyone have stories/tips to make me feel better? Perhaps how you have gotten through it? 😔😑😐14

--- URGENT: Major security flaw in Kubernetes: Update Kubernetes at all costs! ---
Detailed info: https://github.com/kubernetes/...
If you are running any unpatched versions of Kubernetes, you must update now. Anyone might be able to send commands directly to your backend through a forged network request, without even triggering a single line in the log, making their attack practically invisible!
If you are running a version of Kubernetes below 1.10... there is no help for you. Upgrade to a newer version, e.g. 1.12.3.

!!rant
When I worked at a previous job, they only gave out decent titles (and salaries) to upper management. Everyone else... well... I was the Domain/Sysadmin, responsible for the domain and both DCs, upgrading the physical network (plus recabling it: the MDF was a *disaster*), as well as all backups, migrations, printers, servers, and workstations/lappys in the building, plus pushing software, antivirus, updates, security policies, etc. I had complete access to everything, and ofc was responsible for everything. Nothing on my network caused anyone (else) any trouble except one particular printer I wasn't able to replace. Also, nothing new appeared on my network without me noticing and tracking it down.
But my official title? "IT Assistant".
I made $11/hr.
Worth it? Take a flying leap into an overflowing outhouse during the height of a Vegas summer if you even begin to think so.
I eventually managed to switch to a developer position, and (after several attempts) got a ~$5/hr raise. The girl they replaced me with in IT with some ditz who had never installed an OS before, didn't know what the BIOS was, and couldn't figure out why a monitor... plugged into itself... wasn't working. Things went downhill from there.10 -
3 rants for the price of 1, isn't that a great deal!
1. HP, you braindead fucking morons!!!
So recently I disassembled this HP laptop of mine to unfuck it at the hardware level. Some issues with the hinge that I had to solve. So I had to disassemble not only the bottom of the laptop but also the display panel itself. Turns out that HP - being the certified enganeers they are - made the following fuckups, with probably many more that I didn't even notice yet.
- They used fucking glue to ensure that the bottom of the display frame stays connected to the panel. Cheap solution to what should've been "MAKE A FUCKING DECENT FRAME?!" but a royal pain in the ass to disassemble. Luckily I was careful and didn't damage the panel, but the chance of that happening was most certainly nonzero.
- They connected the ribbon cables for the keyboard in such a way that you have to reach all the way into the spacing between the keyboard and the motherboard to connect the bloody things. And some extra spacing on the ribbon cables to enable servicing with some room for actually connecting the bloody things easily.. as Carlos Mantos would say it - M-m-M, nonoNO!!!
- Oh and let's not forget an old flaw that I noticed ages ago in this turd. The CPU goes straight to 70°C during boot-up but turning on the fan.. again, M-m-M, nonoNO!!! Let's just get the bloody thing to overheat, freeze completely and force the user to power cycle the machine, right? That's gonna be a great way to make them satisfied, RIGHT?! NO MOTHERFUCKERS, AND I WILL DISCONNECT THE DATA LINES OF THIS FUCKING THING TO MAKE IT SPIN ALL THE TIME, AS IT SHOULD!!! Certified fucking braindead abominations of engineers!!!
Oh and not only that, this laptop is outperformed by a Raspberry Pi 3B in performance, thermals, price and product quality.. A FUCKING SINGLE BOARD COMPUTER!!! Isn't that a great joke. Someone here mentioned earlier that HP and Acer seem to have been competing for a long time to make the shittiest products possible, and boy they fucking do. If there's anything that makes both of those shitcompanies remarkable, that'd be it.
2. If I want to conduct a pentest, I don't want to have to relearn the bloody tool!
Recently I did a Burp Suite test to see how the devRant web app logs in, but due to my Burp Suite being the community edition, I couldn't save it. Fucking amazing, thanks PortSwigger! And I couldn't recreate the results anymore due to what I think is a change in the web app. But I'll get back to that later.
So I fired up bettercap (which works at lower network layers and can conduct ARP poisoning and DNS cache poisoning) with the intent to ARP poison my phone and get the results straight from the devRant Android app. I haven't used this tool since around 2017 due to the fact that I kinda lost interest in offensive security. When I fired it up again a few days ago in my PTbox (which is a VM somewhere else on the network) and today again in my newly recovered HP laptop, I noticed that both hosts now have an updated version of bettercap, in which the options completely changed. It's now got different command-line switches and some interactive mode. Needless to say, I have no idea how to use this bloody thing anymore and don't feel like learning it all over again for a single test. Maybe this is why users often dislike changes to the UI, and why some sysadmins refrain from updating their servers? When you have users of any kind, you should at all times honor their installations, give them time to change their individual configurations - tell them that they should! - in other words give them a grace time, and allow for backwards compatibility for as long as feasible.
3. devRant web app!!
As mentioned earlier I tried to scrape the web app's login flow with Burp Suite but every time that I try to log in with its proxy enabled, it doesn't open the login form but instead just makes a GET request to /feed/top/month?login=1 without ever allowing me to actually log in. This happens in both Chromium and Firefox, in Windows and Arch Linux. Clearly this is a change to the web app, and a very undesirable one. Especially considering that the login flow for the API isn't documented anywhere as far as I know.
So, can this update to the web app be rolled back, merged back to an older version of that login flow or can I at least know how I'm supposed to log in to this API in order to be able to start developing my own client?6 -
Had a discussion with a developer about security. His software transfers all user data (password and files) unencrypted, so anyone can grab them with wireshark. I told him that this is a severe issue. He said no its no problem because if you get hacked its your own fault, because you probably used an insecure network. NO ! YOU FUCKING MALADJUSTED SHEEP-MOLESTING OBJECT OF EXECRATION, YOU SHOULD ALWAYS ENCRYPT SENSITIVE USERDATA NO MATTER WHAT NETWORK YOU USE. FUCKING KILL ME ALREADY.
Not implementing encryption is one thing but then acting like its no problem is a fucking nother one. Why do people not understand that security of userdata is important???11 -

Security rant ahead - you have been warned.
It never fails to amuse and irritate me that, despite being in the 2019 supposed information age, people still don't understand or care about their security.
I've travelled to a lot of ports and a lot of countries, but, at EVERY port, without fail, there will be at least one wifi that:
- Has default name/password that has been cracked already (Thomson/SpeedTouch/Netfaster etc)
- Has a phone number as password (reduces crack time to 15-30 mins)
- Someone, to this day, has plain old WEP
I am not talking about cafeteria/store wifi but home networks. WTF people?! I can check my email (through VPN, of course) but it still bugs me. I have relented to try and snoop around the network - I can get carried away, which is bad. Still...
The speed is great though :P9 -
I've got a confession to make.
A while ago I refurbished this old laptop for someone, and ended up installing Bodhi on it. While I was installing it however, I did have some wicked thoughts..
What if I could ensure that the system remains up-to-date by running an updater script in a daily cron job? That may cause the system to go unstable, but at least it'd be up-to-date. Windows Update for Linux.
What if I could ensure that the system remains protected from malware by periodically logging into it and checking up, and siphoning out potential malware code? The network proximity that's required for direct communication could be achieved by offering them free access to one of my VPN servers, in the name of security or something like that. Permanent remote access, in the name of security. I'm not sure if Windows has this.
What if I could ensure that the system remains in good integrity by disabling the user from accessing root privileges, and having them ask me when they want to install a piece of software? That'd make the system quite secure, with the only penetration surface now being kernel exploits. But it'd significantly limit what my target user could do with their own machine.
At the end I ended up discarding all of these thoughts, because it'd be too much work to implement and maintain, and it'd be really non-ethical. I felt filthy from even thinking about these things. But the advantages of something like this - especially automated updates, which are a real issue on my servers where I tend to forget to apply them within a couple of weeks - can't just be disregarded. Perhaps Microsoft is on to something?11 -
Worst code review experience?
Hard to pick just one, but most were in a big meeting room with 4+ other developers not related to the project and with some playing Monday-Morning-Quarterback instead of offering productive feedback.
In one code review, the department mgr reviewed the code from a third party component library.
<brings up the code on the big screen>
Mgr: "I can't read any of this, its a mix of English and something else."
Me: "Its German."
Mgr: "Then why is 'Button' in English? This code is a mess."
Me: "I'm not exactly sure how I should respond, I mean, I didn't write any of this code."
Mgr: "Yes, but you are using it, so it's fair game for a code review."
Me: "Its not really open source, but we can make requests if you found something that needs to be addressed."
Mgr: "Oh yes, all this...whatever this is..<pointing again to the German>"
Me: "I don't think they will change their code to English just so you can read it."
Mgr: "We paid good money, you bet your ass they'll change it!"
Me: "I think the components were like $30 for the unlimited license. They'll tell us to go to hell first. Is there something about my code you want to talk about?"
Mgr: "<Ugggh>...I guess not, I couldn't get past all that German. Why didn't we go with an American company? Hell, why didn't we just write these components ourselves!?"
Me: "Because you gave a directive that if we found components that saved us time, to put in a request, and you approved the request. The company is American, they probably outsourced or hired German developers. I don't know and not sure why we care."
Mgr: "Security! What if they are sending keystrokes back to their servers!"
Me: "Did you see any http or any network access?"
Mgr: "How could I? The code is in German!"
Monday-Morning-Quarterback1: "If it were me, I would have written the components myself and moved on"
Me: "No, I don't think you could for less than $30"
Monday-Morning-Quarterback2: "Meh...we get paid anyway. Just add the time to the estimate."
Mgr: "Exactly! Why do we even have developers who can't read this mess."
Me: "Oh good Lord! Did anyone review or even look at my code for this review!?"
<silence>
Mgr: "Oh...ok...I guess we're done here. Thanks everyone."
<everyone starts to leave>
Me: "Whoa!...wait a sec..am I supposed to do something?"
Mgr: "Get that company to write their code in English so we can read it. You have their number, call em'...no...wait...give me their number. You keep working, I'll take care of this personally"
In they nicest way possible, the company did tell him to go to hell.17 -
I've been pleading for nearly 3 years with our IT department to allow the web team (me and one other guy) to access the SQL Server on location via VPN so we could query MSSQL tables directly (read-only mind you) rather than depend on them to give us a 100,000+ row CSV file every 24 hours in order to display pricing and inventory per store location on our website.
Their mindset has always been that this would be a security hole and we'd be jeopardizing the company. (Give me a break! There are about a dozen other ways our network could be compromised in comparison to this, but they're so deeply forged in M$ server and active directories that they don't even have a clue what any decent script kiddie with a port sniffer and *nix could do. I digress...)
So after three years of pleading with the old IT director, (I like the guy, but keep in mind that I had to teach him CTRL+C, CTRL+V when we first started building the initial CSV. I'm not making that up.) he retired and the new guy gave me the keys.
Worked for a week with my IT department to get Openswan (ipsec) tunnel set up between my Ubuntu web server and their SQL Server (Microsoft). After a few days of pulling my hair out along with our web hosting admins and our IT Dept staff, we got them talking.
After that, I was able to install a dreamfactory instance on my web server and now we have REST endpoints for all tables related to inventory, products, pricing, and availability!
Good things come to those who are patient. Now if I could get them to give us back Dropbox without having to socks5 proxy throug the web server, i'd be set. I'll rant about that next.

Long rant ahead.. so feel free to refill your cup of coffee and have a seat 🙂
It's completely useless. At least in the school I went to, the teachers were worse than useless. It's a bit of an old story that I've told quite a few times already, but I had a dispute with said teachers at some point after which I wasn't able nor willing to fully do the classes anymore.
So, just to set the stage.. le me, die-hard Linux user, and reasonably initiated in networking and security already, to the point that I really only needed half an ear to follow along with the classes, while most of the time I was just working on my own servers to pass the time instead. I noticed that the Moodle website that the school was using to do a big chunk of the course material with, wasn't TLS-secured. So whenever the class begins and everyone logs in to the Moodle website..? Yeah.. it wouldn't be hard for anyone in that class to steal everyone else's credentials, including the teacher's (as they were using the same network).
So I brought it up a few times in the first year, teacher was like "yeah yeah we'll do it at some point". Shortly before summer break I took the security teacher aside after class and mentioned it another time - please please take the opportunity to do it during summer break.
Coming back in September.. nothing happened. Maybe I needed to bring in more evidence that this is a serious issue, so I asked the security teacher: can I make a proper PoC using my machines in my home network to steal the credentials of my own Moodle account and mail a screencast to you as a private disclosure? She said "yeah sure, that's fine".
Pro tip: make the people involved sign a written contract for this!!! It'll cover your ass when they decide to be dicks.. which spoiler alert, these teachers decided they wanted to be.
So I made the PoC, mailed it to them, yada yada yada... Soon after, next class, and I noticed that my VPN server was blocked. Now I used my personal VPN server at the time mostly to access a file server at home to securely fetch documents I needed in class, without having to carry an external hard drive with me all the time. However it was also used for gateway redirection (i.e. the main purpose of commercial VPN's, le new IP for "le onenumity"). I mean for example, if some douche in that class would've decided to ARP poison the network and steal credentials, my VPN connection would've prevented that.. it was a decent workaround. But now it's for some reason causing Moodle to throw some type of 403.
Asked the teacher for routers and switches I had a class from at the time.. why is my VPN server blocked? He replied with the statement that "yeah we blocked it because you can bypass the firewall with that and watch porn in class".
Alright, fair enough. I can indeed bypass the firewall with that. But watch porn.. in class? I mean I'm a bit of an exhibitionist too, but in a fucking class!? And why right after that PoC, while I've been using that VPN connection for over a year?
Not too long after that, I prematurely left that class out of sheer frustration (I remember browsing devRant with the intent to write about it while the teacher was watching 😂), and left while looking that teacher dead in the eyes.. and never have I been that cold to someone while calling them a fucking idiot.
Shortly after I've also received an email from them in which they stated that they wanted compensation for "the disruption of good service". They actually thought that I had hacked into their servers. Security teachers, ostensibly technical people, if I may add. Never seen anyone more incompetent than those 3 motherfuckers that plotted against me to save their own asses for making such a shitty infrastructure. Regarding that mail, I not so friendly replied to them that they could settle it in court if they wanted to.. but that I already knew who would win that case. Haven't heard of them since.
So yeah. That's why I regard those expensive shitty pieces of paper as such. The only thing they prove is that someone somewhere with some unknown degree of competence confirms that you know something. I think there's far too many unknowns in there.
Nowadays I'm putting my bets on a certification from the Linux Professional Institute - a renowned and well-regarded certification body in sysadmin. Last February at FOSDEM I did half of the LPIC-1 certification exam, next year I'll do the other half. With the amount of reputation the LPI has behind it, I believe that's a far better route to go with than some random school somewhere.25 -
Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.
That time when...
He wrote a social media network with end-to-end encryption before it was cool.
He wrote custom 64kb encryption for his academic HDD.
He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.
He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).
He used only hashes of passwords as passwords (which isn't actually good).
He kept a drill on the desk ready to destroy his HDD at a moments notice.
He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.
He set up a new email account for each individual online service.
He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).
He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).
He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).
He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.
He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.
He bought a burner phone to visit the capital city.
He bought a burner phone whenever he left his hometown come to think of it.
He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).
He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.
(You might be noticing it's all he's. Maybe it is, maybe it isn't).
He ate a sim card.
He brought a balaclava to pentesting training (it was pretty meme).
He printed out his source code as a manual read-only method.
He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).
He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).
He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.
I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.

The website for our biggest client went down and the server went haywire. Though for this client we don’t provide any infrastructure, so we called their it partner to start figuring this out.
They started blaming us, asking is if we had upgraded the website or changed any PHP settings, which all were a firm no from us. So they told us they had competent people working on the matter.
TL;DR their people isn’t competent and I ended up fixing the issue.
Hours go by, nothing happens, client calls us and we call the it partner, nothing, they don’t understand anything. Told us they can’t find any logs etc.
So we setup a conference call with our CXO, me, another dev and a few people from the it partner.
At this point I’m just asking them if they’ve looked at this and this, no good answer, I fetch a long ethernet cable from my desk, pull it to the CXO’s office and hook up my laptop to start looking into things myself.
IT partner still can’t find anything wrong. I tail the httpd error log and see thousands upon thousands of warning messages about mysql being loaded twice, but that’s not the issue here.
Check top and see there’s 257 instances of httpd, whereas 256 is spawned by httpd, mysql is using 600% cpu and whenever I try to connect to mysql through cli it throws me a too many connections error.
I heard the IT partner talking about a ddos attack, so I asked them to pull it off the public network and only give us access through our vpn. They do that, reboot server, same problems.
Finally we get the it partner to rollback the vm to earlier last night. Everything works great, 30 min later, it crashes again. At this point I’m getting tired and frustrated, this isn’t my job, I thought they had competent people working on this.
I noticed that the db had a few corrupted tables, and ask the it partner to get a dba to look at it. No prevail.
5’o’clock is here, we decide to give the vm rollback another try, but first we go home, get some dinner and resume at 6pm. I had told them I wanted to be in on this call, and said let me try this time.
They spend ages doing the rollback, and then for some reason they have to reconfigure the network and shit. Once it booted, I told their tech to stop mysqld and httpd immediately and prevent it from start at boot.
I can now look at the logs that is leading to this issue. I noticed our debug flag was on and had generated a 30gb log file. Tail it and see it’s what I’d expect, warmings and warnings, And all other logs for mysql and apache is huge, so the drive is full. Just gotta delete it.
I quietly start apache and mysql, see the website is working fine, shut it down and just take a copy of the var/lib/mysql directory and etc directory just go have backups.
Starting to connect a few dots, but I wasn’t exactly sure if it was right. Had the full drive caused mysql to corrupt itself? Only one way to find out. Start apache and mysql back up, and just wait and see. Meanwhile I fixed that mysql being loaded twice. Some genius had put load mysql.so at the top and bottom of php ini.
While waiting on the server to crash again, I’m talking to the it support guy, who told me they haven’t updated anything on the server except security patches now and then, and they didn’t have anyone familiar with this setup. No shit, it’s running php 5.3 -.-
Website up and running 1.5 later, mission accomplished.6 -

I've been away, lurking at the shadows (aka too lazy to actually log in) but a post from a new member intrigued me; this is dedicated to @devAstated . It is erratic, and VERY boring.
When I resigned from the Navy, I got a flood of questions from EVERY direction, from the lower rank personnel and the higher ups (for some reason, the higher-ups were very interested on what the resignation procedure was...). A very common question was, of course, why I resigned. This requires a bit of explaining (I'll be quick, I promise):
In my country, being in the Navy (or any public sector) means you have a VERY stable job position; you can't be fired unless you do a colossal fuck-up. Reduced to non-existent productivity? No problem. This was one of the reasons for my resignation, actually.
However, this is also used as a deterrent to keep you in, this fear of lack of stability and certainty. And this is the reason why so many asked me why I left, and what was I going to do, how was I going to be sure about my job security.
I have a simple system. It can be abused, but if you are careful, it may do you and your sanity good.
It all begins with your worth, as an employee (I assume you want to go this way, for now). Your worth is determined by the supply of your produced work, versus the demand for it. I work as a network and security engineer. While network engineers are somewhat more common, security engineers are kind of a rarity, and the "network AND security engineer" thing combined those two paths. This makes the supply of my work (network and security work from the same employee) quite limited, but the demand, to my surprise, is actually high.
Of course, this is not something easy to achieve, to be in the superior bargaining position - usually it requires great effort and many, many sleepless nights. Anyway....
Finding a field that has more demand than there is supply is just one part of the equation. You must also keep up with everything (especially with the tech industry, that changes with every second). The same rules apply when deciding on how to develop your skills: develop skills that are in short supply, but high demand. Usually, such skills tend to be very difficult to learn and master, hence the short supply.
You probably got asleep by now.... WAKE UP THIS IS IMPORTANT!
Now, to job security: if you produce, say, 1000$ of work, then know this:
YOU WILL BE PAID LESS THAN THAT. That is how the company makes profit. However, to maximize YOUR profit, and to have a measure of job security, you have to make sure that the value of your produced work is high. This is done by:
- Producing more work by working harder (hard method)
- Producing more work by working smarter (smart method)
- Making your work more valuable by acquiring high demand - low supply skills (economics method)
The hard method is the simplest, but also the most precarious - I'd advise the other two. Now, if you manage to produce, say, 3000$ worth of work, you can demand for 2000$ (numbers are random).
And here is the thing: any serious company wants employees that produce much more than they cost. The company will strive to pay them with as low a salary as it can get away with - after all, a company seeks to maximize its profit. However, if you have high demand - low supply skills, which means that you are more expensive to be replaced than you are to be paid, then guess what? You have unlocked god mode: the company needs you more than you need the company. Don't get me wrong: this is not an excuse to be unprofessional or unreasonable. However, you can look your boss in the eye. Believe me, most people out there can't.
Even if your company fails, an employee with valuable skills that brings profit tends to be snatched very quickly. If a company fires profitable employees, unless it hires more profitable employees to replace them, it has entered the spiral of death and will go bankrupt with mathematical certainty. Also, said fired employees tend to be absorbed quickly; after all, they bring profit, and companies are all about making the most profit.
It was a long post, and somewhat incoherent - the coffee buzz is almost gone, and the coffee crash is almost upon me. I'd like to hear the insight of the veterans; I estimate that it will be beneficial for the people that start out in this industry.2 -
My school just tried to hinder my revision for finals now. They've denied me access just today of SSHing into my home computer. Vim & a filesystem is soo much better than pen and paper.
So I went up to the sysadmin about this. His response: "We're not allowing it any more". That's it - no reason. Now let's just hope that the sysadmin was dumb enough to only block port 22, not my IP address, so I can just pick another port to expose at home. To be honest, I was surprised that he even knew what SSH was. I mean, sure, they're hired as sysadmins, so they should probably know that stuff, but the sysadmins in my school are fucking brain dead.
For one, they used to block Google, and every other HTTPS site on their WiFi network because of an invalid certificate. Now it's even more difficult to access google as you need to know the proxy settings.
They switched over to forcing me to remote desktop to access my files at home, instead of the old, faster, better shared web folder (Windows server 2012 please help).
But the worst of it includes apparently having no password on their SQL server, STORING FUCKING PASSWORDS IN PLAIN TEXT allowing someone to hijack my session, and just leaving a file unprotected with a shit load of people's names, parents, and home addresses. That's some super sketchy illegal shit.
So if you sysadmins happen to be reading this on devRant, INSTEAD OF WASTING YOUR FUCKING TIME BLOCKING MORE WEBSITES THAN THEIR ARE LIVING HUMANS, HOW ABOUT TRY UPPING YOUR SECURITY, PASSWORDS LIKE "", "", and "gryph0n" ARE SHIT - MAKE IT BETTER SO US STUDENTS CAN ACTUALLY BROWSE MORE FREELY - I THINK I WANT TO PASS, NOT HAVE EVERY OTHER THING BLOCKED.
Thankfully I'm leaving this school in 3 weeks after my last exam. Sure, I could stay on with this "highly reputable" school, but I don't want to be fucking lied to about computer studies, I don't want to have to workaround your shitty methods of blocking. As far as I can tell, half of the reputation is from cheating. The students and sysadmins shouldn't have to have an arms race between circumventing restrictions and blocking those circumventions. Just make your shit work for once.
**On second thought, actually keep it like that. Most of the people I see in the school are c***s anyway - they deserve to have half of everything they try to do censored. I won't be around to care soon.**2 -

---WiFi Vision: X-Ray Vision using ambient WiFi signals now possible---
“X-Ray Vision” using WiFi signals isn’t new, though previous methods required knowledge of specific WiFi transmitter placements and connection to the network in question. These limitations made WiFi vision an unlikely security breach, until now.
Cybersecurity researchers at the University of California and University of Chicago have succeeded in detecting the presence and movement of human targets using only ambient WiFi signals and a smartphone.
The researchers designed and implemented a 2-step attack: the 1st step uses statistical data mining from standard off-the-shelf smartphone WiFi detection to “sniff” out WiFi transmitter placements. The 2nd step involves placement of a WiFi sniffer to continuously monitor WiFi transmissions.
Three proposed defenses to the WiFi vision attack are Geofencing, WiFi rate limiting, and signal obfuscation.
Geofencing, or reducing the spatial range of WiFi devices, is a great defense against the attack. For its advantages, however, geofencing is impractical and unlikely to be adopted by most, as the simplest geofencing tactic would also heavily degrade WiFi connectivity.
WiFi rate limiting is effective against the 2nd step attack, but not against the 1st step attack. This is a simple defense to implement, but because of the ubiquity of IoT devices, it is unlikely to be widely adopted as it would reduce the usability of such devices.
Signal obfuscation adds noise to WiFi signals, effectively neutralizing the attack. This is the most user-friendly of all proposed defenses, with minimal impact to user WiFi devices. The biggest drawback to this tactic is the increased bandwidth of WiFi consumption, though compared to the downsides of the other mentioned defenses, signal obfuscation remains the most likely to be widely adopted and optimized for this kind of attack.

Taking IT classes in college. The school bought us all lynda and office365 accounts but we can't use them because the classroom's network has been severed from the Active Directory server that holds our credentials. Because "hackers." (The non-IT classrooms don't have this problem, but they also don't need lynda accounts. What gives?)
So, I got bored, and irritated, so I decided to see just how secure the classroom really was.
It wasn't.
So I created a text file with the following rant and put it on the desktop of the "locked" admin account. Cheers. :)
1. don't make a show of "beefing up security" because that only makes people curious.
I'm referring of course to isolating the network. This wouldn't be a problem except:
2. don't restrict the good guys. only the bad guys.
I can't access resources for THIS CLASS that I use in THIS CLASS. That's a hassle.
It also gives me legitimate motivation to try to break your security.
3. don't secure it if you don't care. that is ALSO a hassle.
I know you don't care because you left secure boot off, no BIOS password, and nothing
stopping someone from using a different OS with fewer restrictions, or USB tethering,
or some sort malware, probably, in addition to security practices that are
wildly inconsistent, which leads me to the final and largest grievance:
4. don't give admin priveledges to an account without a password.
seriously. why would you do this? I don't understand.
you at least bothered to secure the accounts that don't even matter,
albeit with weak and publicly known passwords (that are the same on all machines),
but then you went and left the LEAST secure account with the MOST priveledges?
I could understand if it were just a single-user machine. Auto login as admin.
Lots of people do that and have a reason for it. But... no. I just... why?
anyway, don't worry, all I did was install python so I could play with scripting
during class. if that bothers you, trust me, you have much bigger problems.
I mean you no malice. just trying to help.
For real. Don't kick me out of school for being helpful. That would be unproductive.
Plus, maybe I'd be a good candidate for your cybersec track. haven't decided yet.
-- a guy who isn't very good at this and didn't have to be
have a nice day <3
oh, and I fixed the clock. you're welcome.2 -

We got DDoS attacked by some spam bot crawler thing.
Higher ups called a meeting so that one of our seniors could present ways to mitigate these attacks.
- If a custom, "obscure" header is missing (from api endpoints), send back a basic HTTP challenge. Deny all credentials.
- Some basic implementation of rate limiting on the web server
We can't implement DDoS protection at the network level because "we don't even have the new load balancer yet and we've been waiting on that for what... Two years now?" (See: spineless managers don't make the lazy network guys do anything)
So now we implement security through obscurity and DDoS protection... Using the very same machines that are supposed to be protected from DDoS attacks.17 -

Well... I had to visit them for an unrelated matter and found out that they are to pass general inspection the next week. Among the inspectors is a member of the cyber defence team. I took a quick look at the network, finding the things I'd expect:
- No updates passed to the server or installed since I left
- No antivirus updates since I left
- All certificates were expired
- Most services were shut down or unused
- All security policies were shut down
- Passwords (without expiration now) were written on post-it and stuck on screens
- ... and more!
I told the XO (the same idiot that complained about them CONSTANTLY) and he just shrugged me off and told me to """fix""" it. In one fucking afternoon.
I. SHIT. YOU. NOT.
The new admin there is a low ranking person who hasn't the faintest idea of how this works, and isn't willing to learn, either. They just dumped the duty on him, and he seems not to care. The cyber security inspector is going to have a field day. Or get grey hairs.
I told the XO that I needed at least a week to get them into working order (I have to re-set up my virtual Windows 2012 R2 server, download 2 years' worth of updates, repair 2 years of neglect etc.). The answer was what I expected:
"You know computers, you can do your magic and get it done in an afternoon."
Thank god I got transferred and don't have to answer to that idiot any more. Now, popcorn time, as I watch the fireworks.
Yes, I am a vengeful guy. I have told them, twice now, of what would happen. They didn't listen. At least now, with an official report on their heads, they just might.3 -
Classroom fuckery: I'm in a Computer Information Technology program and I usually spend the last hour of class working on code. Most of the people in this program are going into networking or security. This kid looks over and freaks out, starts yelling that I'm breaking into the school's network. I was on freecodecamp.com.5

So I have seen this quite a few times now and posted the text below already, but I'd like to shed some light on this:
If you hit up your dev tools and check the network tab, you might see some repeated API calls. Those calls include a GET parameter named "token". The request looks something like this: "https://domain.tld/api/somecall/..."
You can think of this token as a temporary password, or a key that holds information about your user and other information in the backend. If one would steal a token that belongs to another user, you would have control over his account. Now many complained that this key is visible in the URL and not "encrypted". I'll try to explain why this is, well "wrong" or doesn't impose a bigger security risk than normal:
There is no such thing as an "unencrypted query", well besides really transmitting encrypted data. This fields are being protected by the transport layer (HTTPS) or not (HTTP) and while it might not be common to transmit these fields in a GET query parameter, it's standard to send those tokens as cookies, which are as exposed as query parameters. Hit up some random site. The chance that you'll see a PHP session id being transmitted as a cookie is high. Cookies are as exposed as any HTTP GET or POST Form data and can be viewed as easily. Look for a "details" or "http header" section in your dev tools.
Stolen tokens can be used to "log in" into the website, although it might be made harder by only allowing one IP per token or similar. However the use of such a that token is absolut standard and nothing special devRant does. Every site that offers you a "keep me logged in" or "remember me" option uses something like this, one way or the other. Because a token could have been stolen you sometimes need to additionally enter your current password when doings something security risky, like changing your password. In that case your password is being used as a second factor. The idea is, that an attacker could have stolen your token, but still doesn't know your password. It's not enough to grab a token, you need that second (or maybe thrid) factor. As an example - that's how githubs "sudo" mode works. You have got your token, that grants you more permissions than a non-logged in user has, but to do the critical stuff you need an additional token that's only valid for that session, because asking for your password before every action would be inconvenient when setting up a repo
I hope this helps understanding a bit more of this topic :)
Keep safe and keep asking questions if you fell that your data is in danger

I was told by my manager that I (the guy hired to be the lead developer on this project) was not a developer I was a designer and that writing php instead of using a knockoff version of dreamweever to drag and drop all of the items was an "unsecure and unsafe practice". He screamed at me for another 30 mins over this and then sent me on my way and laid me off a week and a half later after I finished the project because "we can't afford you" I was doing ITS, network and service installs, security, and web development for $10.00 an hour. #stupidboss4

Long rant ahead.. 5k characters pretty much completely used. So feel free to have another cup of coffee and have a seat 🙂
So.. a while back this flash drive was stolen from me, right. Well it turns out that other than me, the other guy in that incident also got to the police 😃
Now, let me explain the smiley face. At the time of the incident I was completely at fault. I had no real reason to throw a punch at this guy and my only "excuse" would be that I was drunk as fuck - I've never drank so much as I did that day. Needless to say, not a very good excuse and I don't treat it as such.
But that guy and whoever else it was that he was with, that was the guy (or at least part of the group that did) that stole that flash drive from me.
Context: https://devrant.com/rants/2049733 and https://devrant.com/rants/2088970
So that's great! I thought that I'd lost this flash drive and most importantly the data on it forever. But just this Friday evening as I was meeting with my friend to buy some illicit electronics (high voltage, low frequency arc generators if you catch my drift), a policeman came along and told me about that other guy filing a report as well, with apparently much of the blame now lying on his side due to him having punched me right into the hospital.
So I told the cop, well most of the blame is on me really, I shouldn't have started that fight to begin with, and for that matter not have drunk that much, yada yada yada.. anyway he walked away (good grief, as I was having that friend on visit to purchase those electronics at that exact time!) and he said that this case could just be classified then. Maybe just come along next week to the police office to file a proper explanation but maybe even that won't be needed.
So yeah, great. But for me there's more in it of course - that other guy knows more about that flash drive and the data on it that I care about. So I figured, let's go to the police office and arrange an appointment with this guy. And I got thinking about the technicalities for if I see that drive back and want to recover its data.
So I've got 2 phones, 1 rooted but reliant on the other one that's unrooted for a data connection to my home (because Android Q, and no bootable TWRP available for it yet). And theoretically a laptop that I can put Arch on it no problem but its display backlight is cooked. So if I want to bring that one I'd have to rely on a display from them. Good luck getting that done. No option. And then there's a flash drive that I can bake up with a portable Arch install that I can sideload from one of their machines but on that.. even more so - good luck getting that done. So my phones are my only option.
Just to be clear, the technical challenge is to read that flash drive and get as much data off of it as possible. The drive is 32GB large and has about 16GB used. So I'll need at least that much on whatever I decide to store a copy on, assuming unchanged contents (unlikely). My Nexus 6P with a VPN profile to connect to my home network has 32GB of storage. So theoretically I could use dd and pipe it to gzip to compress the zeroes. That'd give me a resulting file that's close to the actual usage on the flash drive in size. But just in case.. my OnePlus 6T has 256GB of storage but it's got no root access.. so I don't have block access to an attached flash drive from it. Worst case I'd have to open a WiFi hotspot to it and get an sshd going for the Nexus to connect to.
And there we have it! A large storage device, no root access, that nonetheless can make use of something else that doesn't have the storage but satisfies the other requirements.
And then we have things like parted to read out the partition table (and if unchanged, cryptsetup to read out LUKS). Now, I don't know if Termux has these and frankly I don't care. What I need for that is a chroot. But I can't just install Arch x86_64 on a flash drive and plug it into my phone. Linux Deploy to the rescue! 😁
It can make chrooted installations of common distributions on arm64, and it comes extremely close to actual Linux. With some Linux magic I could make that able to read the block device from Android and do all the required sorcery with it. Just a USB-C to 3x USB-A hub required (which I have), with the target flash drive and one to store my chroot on, connected to my Nexus. And fixed!
Let's see if I can get that flash drive back!
P.S.: if you're into electronics and worried about getting stuff like this stolen, customize it. I happen to know one particular property of that flash drive that I can use for verification, although it wasn't explicitly customized. But for instance in that flash drive there was a decorative LED. Those are current limited by a resistor. Factory default can be say 200 ohm - replace it with one with a higher value. That way you can without any doubt verify it to be yours. Along with other extra security additions, this is one of the things I'll be adding to my "keychain v2".11 -

SeniorDev: “Uh..yea..but it was cleaned up.”
Me: “Your OS might have been compromised. If your antivirus is still busy doing something, then it may be time to start over with a fresh re-install.”
SeniorDev: “No, that’s not it. This is just BS our Network admins don’t want to fix because I’m not a VP”
Me: “I’m pretty sure they don’t care.”
-in as much of a ‘I’m kidding’ tone as I could -
Me: “They would care more if you stopped going to inappropriate web sites on the company computer.”
SeniorDev: “I never go to those sites. It was a link to a charity web site my wife sent me. You know how those sites are. They are built by college kids, so they have no security and was hijacked. That’s how I got the virus.”
Me: “You actually said that to Jim and he believed it?”
SeniorDev: “Well ...yea because….oh …–bleep- you.”
"Jim" sits about 50 feet away, popped his head over the cube wall and smiled. It was awesome. -
My company compromises SSL certificates in the name of "security". I can't even use Gmail because Google has identified my intranet as a malicious network executing a man in the middle attack. So they break security in the name of security.6

Another incident which made a Security Researcher cry
[ NOTE : Check profile to read older incidents ]
-----------------------------------------------------------
So this all started when I was at my home (bunked the office that day xD) and I got a call from a..... Let's call him Fella as I always do . So here we go . And yeah , our Fella is a SysAdmin .
-----------------------------------------------------------
Fella - Hey man sup!
Me - Good going mate , bunked the office , weather's nice , gonna spend time with my girl today . So what's goinon?
Fella - Bruh my network sharing folders ain't working no more .
Me - Did you changed or modified anything?
Fella - Nope
Me - Okay , gimme your login creds lemme check .
Fella - Check your inbox *texts me the credentials*
*I logged in and what I'm seeing is that server runs on Windows2008R2 , checked the event logs , everything's fine and all of a sudden what I found is fucking embarrassing , this wise man closed SMB service*
Me - Did you closed SMB service?
Fella - Yeah
Me - You know what it does?
Fella - Yeah it's a protocol , I turned it off to protect the server from Wannacry .
Me - Fuckerrrr!!!!! Asshole dumbass you fuckin piece of Dodo's shit!! SMB is the service responsible for files and network sharing!!!
Fella - But....I just wanted protection
Me - 😭😭😭
*A long conversation continues with a lot of specially made words to decrease the rate of frustration which I used already*
Fella - Okay I'm turning it on .
Me - Go on....... Asshole
Fella - It worked! Thanks a lot bro
Me - Just leave me and my soul away from evil and hang up .
*Now the question is , who the hell gives them the post of SysAdmin? While thinking this question , I almost thought of committing suicide but then my girl came with coffee and my rubber duck*1 -
I was working in a manufacturing facility where I had hundreds of industrial computers and printers that were between 0 and 20 years old. They were running on their own clean network so that someone has to be in the manufacturing network to access them. The boss announced that the executives will be pushing a “zero trust” security model because they need IoT devices. I told him “A computer running Windows 98 can’t be on the same VLAN as office computers. We can’t harden most of the systems or patch the vulnerabilities. We also can’t reprogram all of the devices to communicate using TLS or encrypt communications.“ Executives got offended that I would even question the decision and be so vocal about it. They hired a team to remove the network hardware and told me that I was overreacting. All of our system support was contracted to India so I was going to be the on-site support person.
They moved all the manufacturing devices to the office network. Then the attacks started. Printers dumped thousands of pages of memes. Ransomware shut down manufacturing computers. Our central database had someone change a serial number for a product to “hello world” and that device got shipped to a customer. SharePoint was attacked in many many ways. VNC servers were running on most computers and occasionally I would see someone remotely poking around and I knew it wasn’t from our team because we were all there.
I bought a case of cheap consumer routers and used them in manufacturing cells to block port traffic. I used Kali on an old computer to scan and patch network vulnerabilities daily.
The worst part was executives didn’t “believe” that there were security incidents. You don’t believe in what you don’t understand right?
After 8 months of responding to security incident after security incident I quit to avoid burning out. This is a company that manufactures and sells devices to big companies like apple and google to install in their network. This isn’t an insignificant company. Security negligence on a level I get angry thinking about.8 -
Was just recalling one of the worst calls I ever got in IT...
Many years ago we had a single rack for all of our servers, network and storage (pre virtualization too!).
We had a new security system installed in the building and the facilities manager let the guy into the server room to run all the sensor cables in because that is where they wanted their panel... the guy was too lazy to get up on the roof and in the attic repeatedly so after he checked it out he went around every where and drilled a hole straight up where he wanted the sensor wire to go... well the server room was not under an attic space... when he found he had drilled through to the out side... HE FILLED IT WITH EXPANDING FOAM.... the membrane on the roof was damaged... that night it rained... I got a call at 4 am that systems were acting funky and I went in... when I opened the door it was literally raining through the corners of the drop ceiling onto the rack... An excellent DR plan saved our asses but the situation cost the vendor's insurance company $30k in dead equipment and another $10k in emergency labor. Good thing for him we had so little equipment in that room back in.
Moral of the story... always have a good DR plan... you never know when it will rain in the server room.... :)3 -
Someone at work asking me about whether the controller system for our door security can access the Internet. I'm explaining that the reason they can't access Google on it is that it is on an isolated network for security. They wanted to install some remote desktop software on it that some idiot had recommended.
Then I actually get asked: "If it can't see Google... Maybe can it see Firefox?"

School's windows installations had the UAC set to lowest.
Anyone could install malware or fiddle with important settings.
Oh by the way, the same school who's gData found it funny to go through my USB drive and delete all executables and all my code because it was "possibly malicious".
Started installing random crap and messing with people in retaliation.
Was fun.
Until I got caught.
Good thing I compiled a list of security flaws earlier on.
From that day on, everytime I messed up, I sold them two security vulnerabilites to let me off the hook.
These included access to all kinds of drives in the windows network, accessing other PCs desktop, literally uninstalling random printers from the network etc..
Fun time.3 -
watching the online course for CEH... dude used the Death Star as a tangible example of how exploits work.
IDK if I should love it for the nerdiness, or be slightly sad that someone needs that type of example of what a vulnerability vs an exploit is, when they're going for the Certified Ethical Hacker certification...
Might be better in an introduction to Network Security class?
Also, while discussing the security, usability, and functionality triangle, he reference the Staples "Easy Button" - does one thing, not very secure, and not very functional (in that it has more than one function)...1 -
//Random Mr. Robot thought//
So this picture and this quote in general has been in my mind quite recently. The first time I saw this scene it just passed through my mind as just a wierd quirk of elliot. But upon further thinking, I question that given Elliot is someone who specializes in network security in a sense. A part of which focuses on finding exploits in networks or even software in general( basically finding the worst in them). And the more I think about that,the more I come to realisation that just like most programmers mix together logic in their life in dealing with people, this scene stands out as an example of just that happening with Elliot and what perhaps, makes him such a good hacker. Perhaps we could all learn from this, or perhaps I'm just looking too much into this. Eh.

Whoever it was that thought that MAC address spoofing/randomization for "muh network security" was a good idea, I'm gonna violently fucking murder them. It doesn't solve jack shit for security, doesn't magically make your network device "anonymous" or whatever and it never fails to confuse my DHCP servers that use those fucking things. Whoever it was, hang yourself or I'll fucking do it for you. Filthy incompetent motherfucker!!13

A few days ago Aruba Cloud terminated my VPS's without notice (shortly after my previous rant about email spam). The reason behind it is rather mundane - while slightly tipsy I wanted to send some traffic back to those Chinese smtp-shop assholes.
Around half an hour later I found that e1.nixmagic.com had lost its network link. I logged into the admin panel at Aruba and connected to the recovery console. In the kernel log there was a mention of the main network link being unresponsive. Apparently Aruba Cloud's automated systems had cut it off.
Shortly afterwards I got an email about the suspension, requested that I get back to them within 72 hours.. despite the email being from a noreply address. Big brain right there.
Now one server wasn't yet a reason to consider this a major outage. I did have 3 edge nodes, all of which had equal duties and importance in the network. However an hour later I found that Aruba had also shut down the other 2 instances, despite those doing nothing wrong. Another hour later I found my account limited, unable to login to the admin panel. Oh and did I mention that for anything in that admin panel, you have to login to the customer area first? And that the account ID used to login there is more secure than the password? Yeah their password security is that good. Normally my passwords would be 64 random characters.. not there.
So with all my servers now gone, I immediately considered it an emergency. Aruba's employees had already left the office, and wouldn't get back to me until the next day (on-call be damned I guess?). So I had to immediately pull an all-nighter and deploy new servers elsewhere and move my DNS records to those ASAP. For that I chose Hetzner.
Now at Hetzner I was actually very pleasantly surprised at just how clean the interface was, how it puts the project front and center in everything, and just tells you "this is what this is and what it does", nothing else. Despite being a sysadmin myself, I find the hosting part of it insignificant. The project - the application that is to be hosted - that's what's important. Administration of a datacenter on the other hand is background stuff. Aruba's interface is very cluttered, on Hetzner it's super clean. Night and day difference.
Oh and the specs are better for the same price, the password security is actually decent, and the servers are already up despite me not having paid for anything yet. That's incredible if you ask me.. they actually trust a new customer to pay the bills afterwards. How about you Aruba Cloud? Oh yeah.. too much to ask for right. Even the network isn't something you can trust a long-time customer of yours with.
So everything has been set up again now, and there are some things I would like to stress about hosting providers.
You don't own the hardware. While you do have root access, you don't have hardware access at all. Remember that therefore you can't store anything on it that you can't afford to lose, have stolen, or otherwise compromised. This is something I kept in mind when I made my servers. The edge nodes do nothing but reverse proxying the services from my LXC containers at home. Therefore the edge nodes could go down, while the worker nodes still kept running. All that was necessary was a new set of reverse proxies. On the other hand, if e.g. my Gitea server were to be hosted directly on those VPS's, losing that would've been devastating. All my configs, projects, mirrors and shit are hosted there.
Also remember that your hosting provider can terminate you at any time, for any reason. Server redundancy is not enough. If you can afford multiple redundant servers, get them at different hosting providers. I've looked at Aruba Cloud's Terms of Use and this is indeed something they were legally allowed to do. Any reason, any time, no notice. They covered all their bases. Make sure you do too, and hope that you'll never need it.
Oh, right - this is a rant - Aruba Cloud you are a bunch of assholes. Kindly take a 1Gbps DDoS attack up your ass in exchange for that termination without notice, will you?5 -
I think I want to quit.
I know it’s a bit of an inconvenient time with there being corona around but everything was okay up till January. I’m a junior even though I shouldn’t be. Since my manager told me and my team leader senior in my review “maybe you two should switch jobs” things have been going downhill. I think the team lead had it out for me and didn’t put me on a new project, I’ve been left with doing stupid basic shit like updating text on websites in a cms and doing fuck all and then there’s also another guy that was basically harassing me trying to put me in my place any time I was doing better than him and literally both of them been like that ... and now that I’m working from home it’s even worse. I don’t have any kind of assurance that everything okay and actually I think I’m being framed as welll since I found keyloggers on my work laptop and deleted cleaned shit up the past two weeks and changed my WiFi security as there were like 5 unknown devices on our network so yeah .. I’ve been framed and they made it out like I put a powershell script on one of the servers and it crashed a Porsche website for 8 h and all kinds of bullshit - this was yday. On Tuesday they logged me out of everything like changed the password for work vpn and kicked me out of slack and Microsoft teams for over 2 hours till the end of shift and two managers weren’t answering their phone and then next day my manager called and apologised that saying that he “accidentally” did that to me along with 15 people they let go from the company....
I’m seriously thinking of quitting being removed from team group for a moment , not being on a project and people literally trying to put me down after I know I’m genuinely smarter than them and if I had over 10 years experience like those on my team (I have 1) I’d be far higher up and better
They can genuinely just go fuck themseves !!!! And here I was going to work over weekend on something! No fucking way I just wanna quit or give in my notice but because of corona I’m divided7 -
So someone decides that the employees need to do these stupid Web-based training's that not even high school kids should be looking into.
What is about ?
Security and Cryptography, and now event the real stuff.
What it covers?
Alice and Bob, Bob and Alice.
Alice wants Bob some pics/messages that she suspects someone else will see. DDDDDDAAAAAAAFFFFFFFAAAAAAAAAKKKKKK
A total of 7 useless time wasting interactive and annoying training's, 20+ min each.
But someone forgot that please do not send this shit to engineers of your company, specially Software/Network engineers. Oh another subset, specially not to those who work deeper into the domain.
I'm getting paid to do this time wasting activity, and still.
I also may come back and remove this BUT FOR NOW I NEED TO RANT. -
I asked the VMware crew at work when we were going to virtualize our network. This was about 5 years ago. I got basically laughed at for suggesting it. I asked when we were going to adopt Azure AD to ensure us being ready for moving to teams etc. Got insults back with how bad the cloud is.
Guess what two projects are getting finalized now? Glad I left that company. Going to enjoy some nice mellow weed, enjoy my 30 day x-mas vacay and jump fresh at a new position. New upstart with a security maker for the maritime sector. A company that embraces new tech by making it them selfs. New day with aiding in the development of an IoT based solution with cloud support.
Happy holidays peeps.

Oh boy, this is gonna be good:
TL;DR: Digital bailiffs are vulnerable as fuck
So, apparently some debt has come back haunting me, it's a somewhat hefty clai and for the average employee this means a lot, it means a lot to me as well but currently things are looking better so i can pay it jsut like that. However, and this is where it's gonna get good:
The Bailiff sent their first contact by mail, on my company address instead of my personal one (its's important since the debt is on a personal record, not company's) but okay, whatever. So they send me a copy of their court appeal, claiming that "according to our data, you are debtor of this debt". with a URL to their portal with a USERNAME and a PASSWORD in cleartext to the message.
Okay, i thought we were passed sending creds in plaintext to people and use tokenized URL's for initiating a login (siilar to email verification links) but okay! Let's pretend we're a dumbfuck average joe sweating already from the bailiff claims and sweating already by attempting to use the computer for something useful instead of just social media junk, vidya and porn.
So i click on the link (of course with noscript and network graph enabled and general security precautions) and UHOH, already a first red flag: The link redirects to a plain http site with NOT username and password: But other fields called OGM and dossiernumer AND it requires you to fill in your age???
Filling in the received username and password obviously does not work and when inspecting the page... oh boy!
This is a clusterfuck of javascript files that do horrible things, i'm no expert in frontend but nothing from the homebrewn stuff i inspect seems to be proper coding... Okay... Anyways, we keep pretending we're dumbasses and let's move on.
I ask for the seemingly "new" credentials and i receive new credentials again, no tokenized URL. okay.
Now Once i log in i get a horrible looking screen still made in the 90's or early 2000's which just contains: the claimaint, a pie chart in big red for amount unpaid, a box which allows you to write an - i suspect unsanitized - text block input field and... NO DATA! The bailiff STILL cannot show what the documents are as evidence for the claim!
Now we stop being the pretending dumbassery and inspect what's going on: A 'customer portal' that does not redirect to a secure webpage, credentials in plaintext and not even working, and the portal seems to have various calls to various domains i hardly seem to think they can be associated with bailiff operations, but more marketing and such... The portal does not show any of the - required by law - data supporting the claim, and it contains nothing in the user interface showing as such.
The portal is being developed by some company claiming to be "specialized in bailiff software" and oh boy oh boy..they're fucked because...
The GDPR requirements.. .they comply to none of them. And there is no way to request support nor to file a complaint nor to request access to the actual data. No DPO, no dedicated email addresses, nothing.
But this is really the ham: The amount on their portal as claimed debt is completely different from the one they came for today, for the sae benefactor! In Belgium, this is considered illegal and is reason enough to completely make the claim void. the siple reason is that it's unjust for the debtor to assess which amount he has to pay, and obviously bailiffs want to make the people pay the highest amount.
So, i sent the bailiff a business proposal to hire me as an expert to tackle these issues and even sent him a commercial bonus of a reduction of my consultancy fees with the amount of the bailiff claim! Not being sneery or angry, but a polite constructive proposal (which will be entirely to my benefit)
So, basically what i want to say is, when life gives you lemons, use your brain and start making lemonade, and with the rest create fertilizer and whatnot and sent it to the lemonthrower, and make him drink it and tell to you it was "yummy yummy i got my own lemons in my tummy"
So, instead of ranting and being angry and such... i simply sent an email to the bailiff, pointing out various issues (the ones6 -
Well, I have a friend working on a major bank in my city. Yesterday we went for a coffee when he told me that the wifi connection that the costumers can use is the same as the network they work in. Like, are you fucking me? Do they know what security means? Jesus Wallace, wake up!
And they have a fucking "web security guy" working there. Doing what? Installing ccleaner on pcs? This shit gets me mad. And that's why I don't trust banks.4 -
A swedish insurance company has two different solution for logging in to their system.
1. An advanced high security single sign on solution involving active directory, verification of the network the request came from etc etc.
2. Using a link and passing your credentials in the query string!!! Like: insurancecompany.com?username=admin&password=password.
Solution 2 works with admin accounts from anywhere.4 -

Omg how stupid some people are... Today at my university I used the first time one of the computers in the computer room and there is a portable Firefox installed in a shared space on the computer and that is also where it saved settings etc. So this is the same for every user on that particular computer.
And when I checked the security settings I found that about 10 different accounts were saved and accessible with website username and password.
So of course the shared space Firefox is bad, but you still shouldn't save you password on a public computer :S
PS: If anyone needs a webmail account or an account for the german university network contact me :P4 -
Finally found my topic for the 10 min presentation :
Network protocol security
After giving an overview , i'm gonna talk about http , ftp , telnet , netbios and showing them a sample packet and how easy the username and password can be found if these protocols are used.
Any other recommandation?5 -

I had a wonderful run-in with corporate security at a credit card processing company last year (I won't name them this time).
I was asked design an application that allowed users in a secure room to receive instructions for putting gift cards into envelopes, print labels and send the envelopes to the post. There were all sorts of rules about what combinations of cards could go in which envelopes etc etc, but that wasn't the hard part.
These folks had a dedicated label printer for printing the address labels, in their secure room.
The address data was in a database in the server room.
On separate networks.
And there was absolutely no way that the corporate security folks would let an application that had access to a printer that was on a different network also have access to the address data.
So I took a look at the legacy application to see what they did, to hopefully use as a precedent.
They had an unsecured web page (no, not an API, a web page) that listed the addresses to be printed. And a Windows application running on the users' PC that was quietly scraping that page to print the labels.
Luckily, it ceased to be an issue for me, as the whole IT department suddenly got outsourced to India, so it became some Indian's problem to solve.2 -

So apparently some major vpn connection providers got compromised some time ago.

https://twitter.com/cryptostorm_is/...
adding the fact that major enterprise vpn network providers had security flaws earlier this year

Sums up what was the major topic in security this year.
At the end I see something like cloud act that allows wiretapping anyone.

And when we multiply this by number of companies that have services in cloud that sums up privacy these days.

CS Teacher today:
"Transport Layer provides Security and Encryption to the communication" (TCP/IP stack)
me: WTF? Encryption is provided on the *top* of the transport layer (aka Application) ( and below [Network Layer] there is IPsec)
Teacher: no, it's wrong.
me: so Wikipedia it's wrong, RFC 5246 is wrong, and you have right?
Teacher: Yes.
me: Ok. (aka fuck you!)2 -
I've noticed looking at the card exit of a building that most people a) just carry their laptop without putting it in the backpack because the carpark is a jump away anyway, b) that stickers on said laptops can leak your infrastructure
No idea what made me interested in that, but if you take the average of people's laptop stickers (sadly not everybody had their laptop or maybe even a laptop at all, so I've got just 20) - you could probably tell what tools and what services the company is running.
Could be a funny coincidence and I was able to verify later by googling their company, but it's an interesting non trackable way to know what services and tools need to be exploited/emulated to possibly gain access to some high security network.
I feel like somebody had to have a talk/presentation about this, so I wonder, had anybody else seen something like that? or how far could this actually go?5 -
Our school had for an open source way of dealing with home schooling and managing the school network and so on.
Now the government forced a "proprietary" system on our school and everyone hates it. The teachers didn't want it the pupils didn't want it but who cares "what we do is the best".
Btw the proprietary system costs a fuck load of money even though they just mixed many open source projects and made it their own proprietary thing.
And this company now get's loads of money for their shitty system that never really worked once since we got it.
They blocked so many ip's that we can't even access google and it's services on the school wifi and the bandwith dropped severely with the new system.
Oh and many random ip's e.g. one of my vps is accessible but the other one not.
Discord is blocked.
Web whatsapp.
And so on...
Now....
I need to learn for tests next week and need to access that stuff on the portal but...
Now they decided to switch the LDAP server to the new system and since a few hours i can't access this fucking thing.
It seems like the platform now contacts the new server which isn't even up and running....
Never change a fucking running system....
Oh and we got smart boards and it runs on android and they didn't block adb. Now i installed clash of clans on one of those things. Haha whoops.

Ibwish I had remembered this when the weekly theme was office pranks.
In the first or second year of high school we covered basic internet security. Stuff like don't follow suspicious urls, don't open suspicious emails and such.
Our teacher let us play around with some sort of simulated desktop environment, where we could execute some hacks like ad popups and such on each other's environment, if we fell for the trap.
Anyways, one hack I found interesting was a hack, that lockes a user out of their virual desktop, until he enters a password, that will be displayed on his environment.
Yes, a very interesting hack, because it contains two obvious yet major design flaws, which I could exploit 😈
1. It's case sensitive
In itself not a problem, but combined with #2, it's fatal.
2. "IlIlllIlI"
Depending on your font, you probably have no idea what exactly I just typed.
Let's just say, the font displayed uppercase i and lowercase L completely undifferentiable.
Guess whom I let suffer.
It was our teacher, who had to demonstrate us some things and who was connected to the same network.
I swear, nothing beats that feeling when your tearcher has go come to you and embarrassingly ask you to "unhack" them, because they can't type it 😂1 -
So let's talk about CNAs, Captive Network Assistants, these downsized browser that open on Smartphones when you try to login to a free wifi which requires you to buy sometging or accept some terms.
I fucking hate them. I'm a web dev which has to deal with these dumbfucks.
Back in the time, there was this dumbfuck who had the idea to capture http requests on network level and response with a redirect to his own landing page. Fuck this guy. Then some dudes had the idea of the CNA as a privacy security feature. A good idea. But also this guys: "hey, let's make them a huge pain to develop for".Fuck them, too. But then came the companies saying: "hey make us a huge SPA with all features we can think of for this fucktard of a browser."
I hate fucking CNAs2 -
New twist on an old favorite.
Background:
- TeamA provides a service internal to the company.
- That service is made accessible to a cloud environment, also has a requirement to be made available to machines on the local network so you can develop against it.
- Company is too cheap/stupid to get a s2s vpn to their cloud provider.
- Company also only hosts production in the cloud, so all other dev is done locally, or on production non-similar infra, local dev is podman.
- They accomplish service connectivity by use of an inordinately complicated edge gateway/router/firewall/message translator/ouija board/julienne fry maker, also controlled by said service team.
Scenario:
Me: "Hey, we're cool with signing requests using an x509 cert. That said, doing so requires different code than connecting to an unsecured endpoint. Please make this service accessible to developer machines and lower environments on the internal network so we can, you know, develop."
TeamA: "The service should be accessible to [cloud ip range]"
Me: "Yes, that's a production range. We need to be able to test the signing code without testing in production"
TeamA: "Can you mock the data?"
Me: "The code we are testing is relating to auth, not business logic"
TeamA: "What are you trying to do?"
Me: "We are trying to test the code that uses the x509 you provide to connect to the service"
TeamA: "Can you deploy to the cloud"
Me: "Again, no, the cloud is only production per policy, all lower environments are in the local data center"
TeamA: "can you try connecting to the gateway?"
Me: "Yes, we have, it's not accessible, it only has public DNS, and only allows [cloud ip range]"
TeamA: "it work when we try it"
Me: "Can you please supply repro steps so we can adjust our process"
TeamA: "Yes, log into the gateway and try issuing the call from there"
Me: (╯°□°)╯︵ ┻━┻
tl;dr: Works on my server -
So, the Network I was on was blocking every single VPN site that I could find so I could not download proton onto my computer without using some sketchy third-party site, so, being left with no options and a tiny phone data plan, I used the one possible remaining option, an online Android emulator. In the emulator running at like 180p I once again navigated to proton VPN, downloaded the windows version, and uploaded it to Firefox send. Opened send on my computer, downloaded the file, installed it, and realized my error, I need access to the VPN site to log in.
In a panic, I went to my phone ready to use what little was left of data plan for security, and was met with no signal indoors. Fuck. New plan. I found a Xfinity wifi thing, and although connecting to a public network freaked me out, I desided to go for it because fuck it. I selected the one hour free pass, logged in, and it said I already used it, what? When?, So I created a new account, logged in, logged into proton, and disconnected, and finally, I was safe.
Fuck the wifi provider for discouraging a right to a private internet and fuck the owner for allowing it. I realize how bad it was to enter my proton account over Xfinity wifi, but I was desperate and desperate times call for desperate means. I have now changed my password and have 2fa enabled.1 -
just found out a vulnerability in the website of the 3rd best high school in my country.
TL;DR: they had burried in some folders a c99 shell.
i am a begginer html/sql/php guy and really was looking into learning a bit here and there about them because i really like problem solving and found out ctfs mainly focus on this part of programming. i am a c++ programmer which does school contest like programming problems and i really enjoy them.
now back on topic.
with this urge to learn more web programming i said to myself what other method to learn better than real life sites! so i did just that. i first checked my school site. right click. inspect element. it seemed the site was made with wordpress. after looking more into the html code for the site i concluded all the images and files i could see on the site were from a folder on the server named 'wp-content/uploads'. i checked the folder. and here it got interesting. i did a get request on the site. saw the details. then i checked the site. bingo! there are 3 folders named '2017', '2018', '2019'. i said to myself: 'i am god.'
i could literally see all the announcements they have made from 2017-2019. and they were organised by month!!! my curiosity to see everything got me to the final destination.
with this adrenaline i thought about another site. in my city i have the 3rd most acclaimed high school in the country. what about checking their security?
so i typed the web address. looked around. again, right click, inspect element and looked around the source code. this time i was more lucky. this site is handmade!!! i was soooo happy because with my school's site i was restricted with what they have made with wordpress and i don't have much experience with it.
amd so i began looking what request the site made for the logos and other links. it seemed all the other links on the site were with this format: www.site.com/index.php?home. and i was very confused and still am. is this referencing some part of the site in the index.php file? is the whole site written inside the index.php file and with the question mark you just get to a part of the site? i don't really get it.
so nothing interesting inside the networking tab, just some stylesheets for the site's design i guess. i switched to the debugger tab and holy moly!! yes, it had that tree structure. very familiar. just like a project inside codeblocks or something familiar with it. and then it clicked me. there was the index.php file! and there was another folder from which i've seen nothing from the network tab. i finally got a lead!! i returned in the network tab, did a request to see the spgm folder and boooom a site appeared and i saw some files and folders from 2016. there was a spgm.js file and a spgm.php file. there was a contrib, flavors, gal and lang folders. then it once again clicked me! the lang folder was las updated this year in february. so i checked the folder and there were some files named lang with the extension named after their language and these files were last updated in 2016 so i left them alone. but there was this little snitch, this little 650K file named after the name of the school's site with the extension '.php' aaaaand it was last modified this year!!!! i was so excited! i thought i found a secret and different design of the site or something completely else! i clicked it and at first i was scared there was this black/red theme going on my screen and something was a little odd. there were no school announcements or event, nononoooo. this was still a tree structured view. at the top of the site it's written '!c99Shell v. 1.0...'
this was a big nono. i saw i could acces all kinds of folders. then i switched to the normal school website and tried to access a folder i have seen named userfiles and got a 403 forbidden error. wopsie. i then switched to the c99 shell website and tried to access the userfiles folder and my boy showed all of its contents. it was nakeeed naked. like very naked. and in the userfiles folder there were all, but i mean ALL files and folders they have on the server. there were a file with the salary of each job available in the school. some announcements. there was a list with all the students which failed classes. there were folders for contests they held. it was an absolute mess and i couldn't believe it.
i stopped and looked at the monitor. what have i done? just to learn some web programming i just leaked the server of the 3rd most famous high school in my country. image a black hat which would have seriously caused more damage. currently i am writing an email to the school to updrage their security because it is reaaaaly bad.
and the journy didn't end here. i 'hacked' the site 2 days ago and just now i thought about writing an email to the school. after i found i could access the WHOLE server i searched for the real attacker so if you want to knkw how this one went let me know in the comments.
sorry for the long post, but couldn't held it anymore13 -
TLDR: I need advice on reasonable salary expectations for sysadmin work in the rural United States.
I need some community advice. I’m the sysadmin at a small (35 employee) credit card processing company. I began as an intern and have now become their full time sysadmin/networking specialist. Since I was hired in January I have:
-migrated their 2007 Exchange server to Office 365
-Upgraded their ailing Windows server 2003 based architecture to 2012R2
-Licensed their unlicensed VMware ESXi servers (which they had already paid for license keys for!!!) and then upgraded them to 6.5 while preventing downtime on hosted VMs using tricky transfers and deployments (without vMotion!)
-Deployed a vCenter server to manage said ESXi servers easier
-Fixed a three month gap in their backups by implementing Veeam, and verifying its functionality
-Migrated a ‘no downtime’ fileserver to a new hypervisor host, implemented a ‘hot standby’ server as a backup kept up to date by the minute with DFS replication.
-Replaced failing hard drives in a RAID array underlying their one ‘business critical’ fileserver, which had no backups for 3 months at that time
-Reorganized Active Directory and Group Policy deployment from a nightmare spiderweb of OUs and duplicate policies
-Documented the entire old network and now the new one as I’ve been upgrading this
-Audited the developers AWS instances and removed redundant machines, optimized load balancing on front end Nginx servers, joined developer run Fedora workstations to the AD domain and implemented centralized syslog monitoring on them.
-Performed network scans and rewrote firewall exceptions to tighten security
There’s more, but you get the idea. I’ve now been tasked with taking point on an upcoming PCI audit which will be my first.
I’m being paid $16/hr US, with marginal health benefits. This is roughly $32,000 a year, before taxes.
I have two years previous work experience managing a third party Apple repair facility (SimplyMac) and every Apple certification for warranty repair and software troubleshooting. I have a two year degree in general sciences, with about 4 years of college credit (Two years of a physics education and two years of computer science after I switched focus) I’m actively pursuing a CCNA and MCSA server 2016 with exams paid for and scheduled.
I’m going into a salary negotiation in two months. What is a reasonable salary to request, from your perspective, for someone in my position?
Thanks in advance!6 -
So I was setting up ELK (Elasticsearch, Logstash and Kibana) all in one EC2 on AWS today for demo purposes. I had everything prepared. Elastic IP, correct security group rules, etc.
I figured I would just do quick test before writing filters and templates if I can access Kibana. So I started service for it and tried to open it with Chrome.
Timeout.
Checked config file. Compared it to documentation. Seemed good but changed some things just for sake of change. Restarted service.
Timeout.
Reverted changes I've made in config. Restarted service. Curl on localhost. It work... OK. 😐
It took me half an hour but finally I figured it out after I took my phone and opened it from there. It was working from the beginning. Stupid company network was for some reason blocking this connection. Fuck! 😡And I was restarting that poor service like crazy trying to fix something that wasn't broken. -
Pentesting for undisclosed company. Let's call them X as to not get us into trouble.
We are students and are doing our first pentest at an actual company instead of assignments at school. So we're very anxious. But today was a good day.
We found some servers with open ports so we checked a few of them out. I had a set of them with a bunch of open ports like ftp and... 8080. Time to check this out.
"please install flash player"... Security risk 1 found!
System seemed to be some monitoring system. Trying to log in using admin admin... Fucking works. Group loses it cause the company was being all high and mighty about being secure af. Other shit is pretty tight though.
Able to see logs, change password, add new superuser, do some searches for USERS_LOGGEDIN_TODAY! I shit you not, the system even had SUGGESTIONS for usernames to search for. One of which had something to do with sftp and auth keys. Unfortunatly every search gave a SQL syntax error. Used sniffing tools to maybe intercept message so we could do some queries of our own but nothing. Query is probably not issued from the local machine.
Tried to decompile the flash file but no luck. Only for some weird lines and a few function names I presume. But decompressing it and opening it in a text editor allowed me to see and search text. No GET or POST found. No SQL queries or name checks or anything we could think of.
That's all I could do for today. So we'll have to think of stuff for next week. We've already planned xss so maybe we can do that on this server as well.
We also found some older network printers with open telnet. Servers with a specific SQL variant with a potential exploit to execute terminal commands and some ftp and smb servers we need to check out next week.
Hella excited about this!
If you guys have any suggestions let us know. We are utter noobs when it comes to this.6 -
For all the hate that Java gets, this *not rant* is to appreciate the Spring Boot/Cloud & Netty for without them I would not be half as productive as I am at my job.
Just to highlight a few of these life savers:
- Spring security: many features but I will just mention robust authorization out of the box
- Netflix Feign & Hystrix: easy circuit breaking & fallback pattern.
- Spring Data: consistent data access patterns & out of the box functionality regardless of the data source: eg relational & document dbs, redis etc with managed offerings integrations as well. The abstraction here is something to marvel at.
- Spring Boot Actuator: Out of the box health checks that check all integrations: Db, Redis, Mail,Disk, RabbitMQ etc which are crucial for Kubernetes readiness/liveness health checks.
- Spring Cloud Stream: Another abstraction for the messaging layer that decouples application logic from the binder ie could be kafka, rabbitmq etc
- SpringFox Swagger - Fantastic swagger documentation integration that allows always up to date API docs via annotations that can be converted to a swagger.yml if need be.
- Last but not least - Netty: Implementing secure non-blocking network applications is not trivial. This framework has made it easier for us to implement a protocol server on top of UDP using Java & all the support that comes with Spring.
For these & many more am grateful for Java & the big big community of devs that love & support it. -
So, my network security faculty thinks s/mime is secure multipurpose internet message encryption. And ssh is secure socket header.
Time to leave the class. 😭1 -
At my institution there is a sys admin that belongs to an entirely different department. They have their own systems on their own network, separated from ours. I do not care, nor do I mind at all, but this is the second time I've had to put their admin in his place.
The first instance was when we had a security firm gauge our systems for vulnerabilities etc. The one that they have was fine, but required some additional configurations on their Tomcat servers. The "sys-admin" contacted I.T (my department) in order to request assistance, the net manager was the one he contacted, and he told the dude that he is not familiar with the Tomcat environment that they have, but that I, the dev manager, would possibly give him some pointers. The net manager is my friend, and he knows how much of a dickhead I am, so he was careful in what he told him. So the dude calls me:
"Hey, I need some items fixed on my Tomcat servers, they told me you have to do it"
Me: "Who? those are your servers"
Him: "The net manager said that you would do it"
Me: "I am certain he didn't tell you that bud, no one here will take care of your servers, they are yours, I am not doing any configurations on your stuff, that is your job"
Him: "Can't you just do them?"
Me: "No, bye"
The little bitch escalated it to my department director, who told him exactly the same thing, the director did ask if I would be willing to assist, I told him no since even though his configurations were minimal, I was not going to put myself in the position to which that fucker's ineptitude would cause him to point fingers at me, director backed me up and told the fucker to deal with his own shit.
This year it came to my attention that not only do they have their owns servers, but their own SSO system. This moron contacted me, tagging VPS and such in the email to tell me that I had to configure his SSO because "they told me you had to do it". The same shit happened, but this time I put him on blast during a meeting and told him that as "sys admin" for his stuff it was his responsibility to deal with the SSO that they have, and to contact the vendor to ask for the specifications. In front of EVERYONE he asked me if I could do it for him, I fucking looooooooled and told him that he just admitted to not being able to do his job (for which he is paid handsomely) in front of the entire room of VPS. One VP asked me why I was not willing to help him, and I told the VP that it would be the equivalent of me taking his vehicle for services, it is not my vehicle, thus not my responsibility. The VP agreed and told the fucker to get on with it and do what I said: contact his vendor channels to figure it out himself since it was indeed his position.
Yet again he said that he didn't know about SSO configs and that he was "told that I would do it", everyone asked who the fuck told him that and he said that the vendor, they asked again how it was and he showed the message from the vendor telling him: "Have your SSO admin perform the following <bla bla bla bla>" they asked him who was the manager for the SSO that they had. He said that it was him. Then they asked him what logic made him believe that it should be me, he stated again "they told me it was him".
I could hear everyone's brains shortcircuiting as no one could believe someone would be this fucking dense.
I don't think he will continue to have his job for much longer. I understand not knowing something, and I would have been happy to give pointers since I do administer systems of that level, but I can't with the whole made up "they said he would do it"
Bitch who said that? just say that you want me to do it because you can't, I mean, I am still not fucking doing it, but damn. Fucking morons man.5 -
I really don't understand this particular Government Department's IT Unit. They have a system and network to maintain except:
- They don't have a DBA
- They don't have a dedicated Network Engineer or Security Staff
- Zero documentation on all of the systems that they are taking care of (its all in each assigned particular staff's brain they said)
- Unsure and untested way of restoring a backup into a system
- Server passwords are too simple and only one person was holding this whole time and its to an Administrator account. No individual user account.
- System was developed by an in-house developer who is now retired and left very little documentation on its usage but nothing on how its setup.
But, the system has been up and operational for the past 20 years and no major issues whatsoever with the users using it. I mean its a super simple system setup from the looks of it.
1 App Server connected to 1 DB Server, to serve 20-30 users. But it contains millions of records (2GB worth of data dump). I'm trying to swing to them to get me on a part time work to fix these gaps.
God save them for another 20 years.3 -
I code. I'm not a network or security admin. Did you even read my resume before hiring me? It says "math degree then data analysis then programming degree" Subnets, firewalls and security certs are not my areas of expertise. Given enough time, could I stumble through? Probably. But I'd probably come up with something worthy of mocking on networkadminrant.

2. got the ipaddress via :
host x
3. nmap -F ip.of.x
my head is already spinning, i need to know what BASICLY each of what i've done. i only get that 'whois' get the information about that domain, 'host' is used to know the target ip address and nmap to find what are the open ports. i don't know what else should i do. need help :(13 -

For what fucking reason the ability to set the date and time programatically has been blocked on Android?!
Why you can create fucking invisible apps that work in the background, mine cryptos, steal your data but they decided that something like that is considered dangerous?
Can anyone give me a logical explanation?
P.S.
There are cases (big pharma companies) where the users don't have access to internet nor a ntp server is available on the local network, so the ability for an app to get the time of a sql server and set it in runtime is crucial, expecially when the user, for security reasons, can't have access to the device settings and change it by himself.
"System apps" can do it, but you would have to change the firmware of a device to sideload an external "System app" and in that case it would lose the warranty.
So, yeah, fucking Google assholes, there are cases where your dumb decisions make the others struggle every other day.
Give more power to third party developers, dumb motherfuckers.
It's not that difficult to ask the user, once, to give the SET_TIME permission.
It was possible in the past...

Windows Mobile 6.5 was a masterpiece for business.

I chose Network/Cyber Security because it was my internship experience and they were willing to pay me good money to stay on... No but seriously I am much better at understanding how complex systems work than coding them. This job, as stressful as it is, is a different kind of stressful that the deadline-fraught jobs of software developers worldwide.
And i can do it fully remote.2 -
So just now I had to focus on a VM running in virt-manager.. common stuff, yeah. It uses a click of le mouse button to focus in, and Ctrl-Alt-L to release focus. Once focused, the VM is all there is. So focus, unfocus, important!
Except Mate also uses Ctrl-L to lock the screen. Now I actually don't know the password to my laptop. Autologin in lightdm and my management host can access both my account and the root account (while my other laptop uses fingerprint authentication to log in, but this one doesn't have it). Conveniently my laptop can also access the management host, provided a key from my password manager.. it makes more sense when you have a lot of laptops, servers and other such nuggets around. The workstations enter a centralized environment and have access to everything else on the network from there.
Point is, I don't know my password and currently this laptop is the only nugget that can actually get this password out of the password store.. but it was locked. You motherfucker for a lock screen! I ain't gonna restart lightdm, make it autologin again and lose all my work! No no no, we can do better. So I took my phone which can also access the management host, logged in as root on my laptop and just killed mate-screensaver instead. I knew that it was just an overlay after all, providing little "real" security. And I got back in!
Now this shows an important security problem. Lock screens obviously have it.. crash the lock screen somehow, you're in. Because behind that (quite literally) is your account, still logged in. Display managers have it too to some extent, since they run as root and can do autologin because root can switch user to anyone else on the system without authentication. You're not elevating privileges by logging in, you're actually dropping them. Just something to think about.. where are we just adding cosmetic layers and where are we actually solving security problems? But hey, at least it helped this time. Just kill the overlay and bingo bango, we're in!2 -
Going back to school to get my degree for Network Security/ Administration.
Which I'm doing right now -
My workplace is still using xml based configuration, and non-spring boot projects.
So every spring boot tutorial I find feels like "Look at how easy you can get this running" and then it's just actually a toy you can't get into production.
Also it kind of bugs me that you need to be online to actually be able to initialize/create a spring boot project and every single tutorial says so.
You can make a local network m2 repository, but can one make a spring initializer service?
Either way, migrating every single project to Spring boot is a no-no,
And I'm stuck with like 5 prototypes of SSO integration from which only 2 work, and the other 3 have their own problems.
One does redirect to the login and all, but the SAML endpoint gets 404 on response when you log in.
One is on OpenID Connect, but I would need to update the project from Spring 3 to Spring 5 to get it working, which upon attempting to do seems to break everything else.
One has an external library handling the security context just the way we are accustomed to, but it only does a 401 forbidden when you go without logging in and I'm starting to think it is actually one of those that require you to extract the token or something manual like that, which wouldn't work for us
The other two are spring boot tutorials that worked out of the box, both SAML and OpenID, still can't use those for the main projects.
I'm tired of dealing with this configuration hell, been two months at this, I want to get features done as usual, not be stuck configuring stuff that might or might not work.
Rant aside, I think I figured I need to use a different Security adapter, but I needed to vent.2 -

So thanks for whoever pointed out my mistake with the “!” operator.
I tried to be devcool but i failed ;) but im allgood now!
Getting to the topic:
After scanning people's opinion here i have decided to learn C.
I have done js react and html css for the last year and have an okay grasp on it but i want to learn more.
Mainly:
-security
-network
-memory and ressources
Im a noob ant ive only scratched the surface. Im gonna be soon working on databases and backend java to master the functioning of a backoffice with its API and the handling of form and crud automisation (i probably am not using all the right words. I am learning and being told what to do).
Am i helping myself with C and if so any tutorial advice or good teaching resource that could be advised to me.
Thanks ;)6 -
Aside from simple programs I wrote by hand-transcribing code from the "Basic Training" section of 3-2-1 Contact magazine when I was a kid in the '80s, I would say the first project I ever undertook on my own that had a meaningful impact on others was when I joined a code migration team when I was 25. It was 2003.
We had a simple migration log that we would need to fill out when we performed any work. It was a spreadsheet, and because Excel is a festering chunk of infected cat shit, the network-shared file would more often than not be locked by the last person to have the file open. One night after getting prompted to open the document read-only again, I decided I'd had it.
I went to a used computer store and paid $75 out of pocket for an old beater, brought it back to the office, hooked it to the network, installed Lunar Linux on it, and built a simple web-based logging application that used a bash-generated flat file backend. Two days later, I had it working well enough to show it to the team, and they unanimously agreed to switch to it, rather than continue to shove Excel's jagged metal dick up our asses.
My boss asked me where I was hosting it, as such an application in company space would have certainly required his approval to procure. I showed him the completely unauthorized Linux machine(remember, this was 2003, when fortune 500 corporations, such as my employer, believed Ballmer's FUD-spew about Linux being a "virus" was real and not nonsense at all), and he didn't even hesitate to back me up and promise to tell the network security gestapo to fuck off if they ever came knocking. They never did.
I was later informed that the team continued to use the application for about five years after I left. -
So I had this Google account for all of clients social, hosting, etc.
Out of the blue client wants access to these accounts.
Unfortunately I had not logged into these accounts in a long time.
Now when I try to login Google is not sending 2f texts to my registered number, even the give code over call option is not working, my number is recieving texts and calls, so it's not a network issue.
To top it all off due to numerous attempts it won't let me try other options and my recovery email recieved security alert of the said attempts with no option of actually specifying it was a legitimate attempt.
Fuck this overly protective attempt at security and fuck the guy who thought it was a good idea to send emails about attempts but not including any option to actually do something about it.6 -
Duck! this sloppy whiny winnfsd.
Yay! Let's use state of the art Docker with a VirtualBox VM on Windows10.
Don't get me wrong.
The Docker containers in this VM doing a great job on performance.
But in the very moment a Docker container uses a mounted folder via the windows network filesystem, all hell is breaking loose.
Building a vendor folder using a composer Docker image with 84 Packages takes about 15 seconds when cache has been warmed up.
The same Docker command pointing on a folder mounted to Windows Filesystem with warmed up cache takes about 10 Minutes!@&&@""+&
And what is the duckin' reason for this delay?
Because every transfer of a teeny tiny file has to establish a connection to fat ass Windows OS and has to pass it's glorious "security" layer.
DUCK it!
For real.
I currently working on a shell script which builds the whole vendor folder on a volume on Docker VM.
After completion, the shell script will compress the folder to one file.
This one file will be transferred over this god damned network filesystem.
Finally the script will unpack the compressed vendor folder in it's destination folder.
*sigh*
What year is it?!??3 -
My work product: Or why I learned to get twitchy around Java...
I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.
Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.
In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.
As if that weren't enough, there's a beanshell interface to allow users to script the test system, but none of the users know Java well enough to feel confident writing interpreted Java scripts (and that's too close to JavaScript for my comfort). I once tried swapping this out for the Rhino JavaScript interpreter and got all the verbal support in the world but no developer time to design an API that'd work for all the departments.
The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.
It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).
We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.
Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.
This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.
The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.
Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.
And... Fucking and!
Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.
Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.
Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.
What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").
Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.
This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?2 -

Our ISP asked if I was satisfied with their service. I told them that it's okay, but some of our computers don't have enough powerful network card, and they can't use the internet on maximum speed, and they said that they could see it, too. WTF? I knew that the ISP's router is not the most secure thing, but it has a remote mode, which if of course OFF, and they still can see this, and maybe even more.

Interesting project lined up for today!
I'll be installing a security system, one camera connected to a DVR pointing at a front door triggering a buzzer and sending a video feed to a monitor in a ground floor room at the other side of the house.
But it's my dads house so I'm going to have fun with it and install a wired Cat5 network an Isolated offline router and build in some "smart home" features from scratch, all running on a Local Area Network.
I've built a private home server package for media and storage using Apache and I want to add as many features to the house as I can, maybe even install an extra camera pointing towards the sky (every home should have a sky cam lol).
I can take my time with this project over the next several weeks and I was wondering what would you add to this project?10 -
Just had a so called "cyber security" seminar in college today.
The guy who claimed to be a trainer or somewhat network security guy or something behaved enigmatically with utter consistency. He obviously claimed to know facebook hax0ring though.

(Ethical Hax0ring Course) (also claimed their site to be 99.9% secured - GREAT!)
After obtaining a ISO*** standard cert or after taking multiple sessions on "advanced ethical hacking" if you go about telling peeps in colleges that: "The single way to hax0r a facebook account is CSRF!" "Will hack your facebook account by MITM through malicious WiFi Ap." Then, NO neither I want your shitty cert nor do I want to be in your team and create the next level of "advanced ethical hax0ring - CEH course". Reason why I get cringed when peeps start about their certs and the ISO*** value it contains. What ISO value does your brain cells contain though? -
My school has a completely open SMTP server. A friend today who works for the tech department just showed me how anyone could fake an email. He did this by sending me an email as the president of the school, it looked legit. He told the security dudes but they can't secure it due to legacy systems. This is madness surely!?! Is open SMTP as bad as I think? (It is at least only accessible on the schools network).3

My company has a board on Blind (semi-anonymous social network for corporate employees). We're a startup and have had two layoffs in the past two years, with very few pay increases.
I voiced my thoughts about the future of the company. We're pulling in a lot of revenue (millions a month) but still have a crazy amount of costs.
Someone responded that a bunch of our revenue ops people left for other companies. Another person replied the director that left had a good opportunity, thought we'd get another round of funding and that the company has had some purchase offers (with valuation being the big sticking point).
If it's true, it should feel like some job security. I can't help but also wonder if anon is lying so people purchase more of their stock options to generate more runway.1 -
I connected oven to wifi using application on my phone but application on my phone didn’t connected to oven.
So now I need to disconnect oven from wifi to connect oven to my phone.
I connected dishwasher last month, first I needed to take a photo of qr code and send it to my laptop to be able to scan it cause it was to small and dishwasher app didn’t recognized it. Looks like dishwasher decided to disconnect from wifi this week so I need to repeat the whole process again.
I also bought connected washing machine and fridge but I think I will try to connect them next month when I manage hopefully to connect my oven.
Seriously home appliances iot is complete shit. Looks like there is no wide known standard of establishing connection so everyone is doing it on it’s own. All this security procedures to connect something to your local network are crap. I hope oven won’t disconnect from wifi.17 -
I MISS TIGERDIRECT! a haiku&rant
Tiger, so direct
Hardware haven, my tech friend
Killed, by poor Insight
I thought I had found ways to cope with it all... became a cert'd refurbisher at enough lesser operations to rebuild some semblance of my hardware connects. I even resorted to newegg to fill small voids... why is it so hard to find a quickly shipping, scriptable, 2 WAN in 6+ channels out, non WiFi noob crap, router... or even an L3 managed switch for <250$ not tied to some bullshit excuse for network management like a "cloud management platform" with some rando 'security' bloat?!?! Not even trying to force the PoE functionality (realistically i know I'll just wire that up myself after procrastinating too long)... i even tried newegg and damn amazon, neither seem to realise that real routers and switches arent interchangeable terms.
I even tried tolerating supporting the murderous, treasonous, obfuscating high prices and insisting you register as your business and let them trap you in the equivalent of a 'free' ski trip, with "short" timeshare presentation.
All bullshit and overpriced af trying to force some bloat down your throat so you "feel" like you're properly managing a network.
Anyone have an ace up their sleeve? For quick delivery (USA) minus bloat, pandering and ass-to-mouth rape???
I even tried stooping to a current Cisco OEM!
I mean, if it was *only* a bit of ass rape, I'm fine with that... but the bloat, pandering and shit-stained lollipop...
I'd rather just disappear from valid business obligations, get somewhat intoxicated, and hyperfocus tear apart my tech graveyards, go ghetto apocalyptic tech macgyver on that shit and emerge days later low on solder, in dire need of a flintstones size whetstone, more arduinos, a tetanus shot and a shower.1 -
This is not a rant. Not really. It's more expressing my own insecurity with a certain topic, which somehow upsets me sometimes (the insecurity, not the topic though).
I have nearly no knowledge about security/privacy stuff. I mean, yeah, I know how to choose secure passwords and don't make stupid DAU mistakes. The very basics you would expect someone to have after a CS bachelor's degree.
But other than that... Nothing. And I would like to get a bit into that stuff, but I have no clue where to start. First getting my head wrapped around low-level stuff like network layers? Or something completely else.
This topic is so intimidating to me as it seems huge, I have no idea where to start, and I feel that if you don't have "full" knowledge, you are going to make mistakes which you might not even notice.
I sometimes get really scared about having an account hijacked or similar. Also in our job it seems to become more and more of a topic we should know about.
Anybody got any advice?
I am looking for a way to improve my knowledge in security in general for professional reasons and my knowledge about privacy for private reasons.
It's just, every time I start reading something related it seems that I am lacking some other knowledge etc...10 -
Welp, Guess I'm back after almost 3 years. I graduated and can now officially call myself a network & security engineer.1
-
In highschool right now and I'm seriously interested in network and information security. I recently managed to work out possible internships at some top security firms based out of sweden. I am super stoked and am excited to see the pros work. Might be interesting.
-
Guys, how did you decide your area of specialisation ? Like working with web apps , or network security or Machine Learning and AI , sys admin etc . I find all of them interesting but never end up knowing them in depth.9
-
Question for all the security/privacy nerds here. What is your opinion of the social network called Minds that pays you for your information basically.
(This is a very brief probably inaccurate summary but yeah, it’s basically reverse Facebook)1 -
I think I have a hacker on my network taking over devices at random and doing stuff while users are logged in and watching. I’m not as up-to-date on this security stuff as I used to be. Running Windows, Mac, and iOS. Any suggestions how I can detect and cut off take-overs like this?1

In college, during Novell's heyday, I was working on my Certified Network Administrator certification (totally worthless, in retrospect). As I was becoming an expert in all things Novell, I found a security flaw. Using Visual Basic it was possible to code up an exact replica of the Novell login screen that launched at boot time from a batch file stored on a floppy. You could log peoples' usernames and passwords all day as long as they didn't realize your floppy was in the drive, which worked in certain computer lab setups on campus. I wasn't in it for stealing info or being a criminal. I just did it for the lulz. But if I had gained access to a few of the right computers in admin offices on campus, I could've gotten access to anyone's student profiles and grades.

I always hated in school computing lessons when the teachers pet students would snitch on you for getting around the school network stuff.
Many people in the lesson would always play games instead of doing what they were meant to. So the teacher turned off the internet in the room using the admin control stuff. Then when I found a way around it all so I could watch some educational YouTube videos, the stupid teachers pet would snitch on me. Luckily the teacher knew I wasn’t using it to mess around, always felt good when he said that I could access it because I’m the biggest security threat to the school.
Did you ever have issues with snitches in computing lessons?6 -
Three Layers of Security
As InfoWorld notes, all smartphones have three basic
elements of security. Your first major task as a mobile
user is to become aware of these layers and enable them
in your devices:
1. Device Protection: Allowing remote data "wiping" if your
device is ever lost or stolen.
2. Data Protection: Preventing corporate data from being
transferred to personal apps running on the same device
or personal network
3. App-Management Security: Protecting your in-app
information from becoming compromised.

Update:
I've been trying to leave DoD for a couple of months now. Translating my 10 year's experience with complex Intelligence enterprise level systems to something relatable to the civilian IT world. Grabbed a few certs to help out A+, network+ and security+ with Linux+ as my next target. Photos of me working on unclassified systems, radios, cell towers and servers. I'm a teacher for military UAS so this shouldn't be to hard to get even a basic job in IT right.
No one will hire...
Linux admin: Nope
Network admin: Nope
Assistant Network admin: Nope
IT call service: Nope
Pool cleaner fucking nope
Many interviews and nothing
I'm broke and sold all of my personal valuables. I can't hold out much longer and really looking at becoming homeless. But I'm kinda ok with it, one last payment on my apartment and car is all I can do now. My parents think I'm in Afghanistan working a six figure job lol
DoD: we see you're trying to leave we'll pay you alot to teach A+, Network+ and Security+ traveling all across the country and staying at hotels with all expenses paid.
FU FU FU I want out please tell me someone has a job, I'll be a janitor of a server room Idc I just want out. Fuck the pay
I start Tuesday...4 -
Doing network security and infrastructure(im a dev but our sysadmin resigned so the next person they thought capable is me)...like seriously yesterday Im fixing c# bugs then the next day I find myself having a meeting with system/security admins...i feel so noob :)1

Brave Browser introduced tor integration for private tabs. https://twitter.com/brave/status/...
Is security taking a toll when Tor network is accessed through not the actual Tor browser?2 -
Security experts have discovered hundreds of fake websites which are being used to spread dangerous malware for Android and Windows devices. A "vast" network of over 200 internet pages, which impersonate 27 brands such as household names like TikTok, PayPal and Snapchat, are being used to spread a vicious bug which can empty out bank accounts. These bogus websites feature the notorious ERMAC banking trojan which is capable of stealing sensitive login details for 467 online banking and cryptocurrency apps.9

So i am at an MNC as a summer internship, me along with 18 other students from my university cleared this hackathon and got selected for this internship,
Few things you should know
1. Amongst all the other candidates i had the most work experience
2. I had worked with a lot of python and JavaScript
3. I legit have more skills then almost everyone working in my team
So, I don't know how but the HR decided i should go to this team, where there are no developers and are people of age 30 who have no idea what django is,
I was fucking frustrated but i let it go, thinking i will just solve this problem and will change my team, calm down
They told me about the project. I said okay give me access i will just finish it.
5 days no signs of access anyhow, so, i sucked it up and tracked all the network request and made my own api,
Then I was happy i get rid of this project,
But then they had bigger plans they ask me to add features on this project but there is a catch you have no access to any accounts, do it on your own,
Like What the Fuck, before giving an intern any project don't you have the responsibility to check weather the fucking project is possible i am just wasting my summer internship. I thought I got a big company it will help me grow i will get job security, but noo wtf, i am hell of frustrated1 -
External Storage recommendation questions.
Im in need of some sort of external storage, either a harddrive or a NAS server, but idk what to get.
Price should be reasonable for the security and storage space it gives, so heres what i figured so far for pros and cons:
NAS Server:
+ Bigger capacity
+ Raid option
+ Easily expandable
+ Always accessible via the network (local)
- Difficult to transport (not gonna do that, but still)
- Expensive
- Physically larger
- Consumes power 24/7 (i dont pay for power currently)
Harddrive:
+ Easy to pack away and transport
+ Cheaper
- If drive fails, youre fucked
- If you want larger capacity, you end up with two external backups
What do you guys do? Im not sure what i should do :i
Any advice is appreciated.
It will be used for external backup, as mentioned. For my server and my own pc.12 -
Honestly, I'm kinda sick of programming. I would like to work in some other area of systems engineering, like business intelligence or network security, I don't know. Do you guys have any experience on other fields besides programming?3

Hey all, I'm curious for your opinion on this one. I've got some smart home devices (e.g. Hue lights, Nest Protect) and lately I started to think of the best way to protect them. Now I did see this project on Kickstarter (https://kickstarter.com/projects/...) and it seems to be a nice and easy way. But still, you don't know what they'll do with your data.
Would MAC address filtering in my router / modem not suffice for protection?
Let me know what you think :)5 -
Just what is life
1st I love developing Web Apps
2nd I hate when it has bugs (Always does Everyone does)
3rd More hate for Security related bugs
So I started bug hunting so that even I can make developers hurt I thought I might find peace here
But here we fucking have SQL Injections which are not really that bad easy peasy
But we also have special kind of SQL Injections the Boolean Based ones (Medium Level Demons) and also The Time Based SQL Injections (Medium Level Demon with lots of health consumes too much time has a repetitive process and we have to wait a lot also if you have network lag you are doomed)
No its nice story till here but here it fucking ends the happiness I mean my luck is worst kind of fucking thing anybody ever can have.
I got a mix of both Demons;_;
A Time-Based Boolean SQL Injections yess fuckety amounts of fucking time wasted and redundant fucking process also to make matters worst the fucking famous tool #SQLMAP doesn't work in my case -
So I changed my FB account password and it gave me email notification with an ip address. And then when I logged in it gave me another notification email with a different IP address this time. Should I be concerned about my network security? This is just SO ANNOYING!!!2

So... I got a simple task of choosing the best fitting NIDS/MIDS, as well as deploying it, configuring to fit a specific use case and monitor its outputs for one client at work today...
I'm a little... Anxious. At a first glance, setting up like... Snort... Doesn't seem all that difficult, but I have no idea where this takes me and if what I come up with will ultimately be useful or not... Until now I did simple service configuration changes like apache, nginx, php... And a bit of database management with things like mariadb, mysql, postgresql, mongo or elastic... I feel so... Out of my usual waters.
Do you guys thing a person without a title in network security (or... Any title for that matter) can even manage this?...1 -
Im always trying to learn new things. Im passionate about learning new things, especially development. So much i started a small collaboration group of developers and slack group to collaborate new projects/ideas,get to know new people, and just to learn new things from each other. The group is not language specific developers only, but mostly consists of PHP/Laravel developers at the moment, so im always trying to grow that network as much as possible, so if you would like to join my network to collaborate new ideas or to just even talk to some cool cats, ill send you an invite any day. Anyways, back to my original reason for this post. Im mid level developer who considers himself pretty knowledgeable in PHP and Laravel. Im curious to what other developers use to learn new things. Im constantly questioning my skillset and compare myself to senior developers who always blow me away with their knowledge which often makes me feel like i dont know enough. Currently I use resources such as:
-laracasts.com
-serversforhackers.com
-digital ocean articles or any textbook that wont cost me an arm and a leg lol
I mean i just want to learn about tech related stuff always but currently interested in learning specifically about development topics such as:
- Server administration because i would consider this my weakest skill set (things like provisioning,nginx/security, deployment)
- Continous Integration (as ive never been at a job that practices it)
- RESTful APIs(as ive never developed one)
and so much more but i wont waste your time with my never ending list. What resources/tools do you guys use for your learning?6 -
Though I’ve seen devices like the following I’ve only ever seen them used for horrible purposes.
I was envisioning facility control being made capable by the use of a larger tablet device or tablet computer. The device would have no internet connection. It would not attach to the outside world at all.
It would not receive non manual software updates
It could view all air flow, temperature, lights, locks, electrical outlets, power draw, water usage, heaters, air conditioners, computer statins etc
And control and report statistics on them all.
Impractical you people said last time. But I would say cool if the device is kept super secure . That being said who knows how to do that since everything sucks once someone who knows what they’re doing has physical access lol
Personally all I don’t know how to break into is smart phones
Comps I could always figure out even if they had disk encryption given enough time.
The only reason phones are hard is you’re limited to network attacks and the boot loader is on the chip page.
Cause in the end a computer is just it’s hard drive in terms of security lol1 -
So as a personal project for work I decided to start data logging facility variables, it's something that we might need to pickup at some point in the future so decided to take the initiative since I'm the new guy.
I setup some basic current loop sensors are things like gas line pressures for bulk nitrogen and compressed air but decided to go with a more advanced system for logging the temperature and humidity in the labs. These sensors come with 'software' it's a web site you host internally. Cool so I just need to build a simple web server to run these PoE sensors. No big deal right, it's just an IIS service. Months after ordering Server 2019 though SSC I get 4 activation codes 2 MAK and 2 KMS. I won the lottery now i just have to download the server 2019 retail ISO and... Won't take the keys. Back to purchasing, "oh I can download that for you, what key is yours". Um... I dunno you sent me 4 Can I just get the link, "well you have to have a login". Ok what building are you in I'll drive over with a USB key (hoping there on the same campus), "the download keeps stopping, I'll contact the IT service in your building". a week later I get an install ISO and still no one knows that key is mine. Local IT service suggests it's probably a MAK key since I originally got a quote for a retail copy and we don't run a KMS server on the network I'm using for testing. We'll doesn't windows reject all 4 keys then proceed to register with a non-existent KMS server on the network I'm using for testing. Great so now this server that is supposed to connected to a private network for the sensors and use the second NIC for an internet connection has to be connected to the old network that I'm using for testing because that's where the KMS server seems to be. Ok no big deal the old network has internet except the powers that be want to migrate everything to the new more secure network but I still need to be connected to the KMS server because they sent me the wrong key. So I'm up to three network cards and some of my basic sensors are running on yet another network and I want to migrate the management software to this hardware to have all my data logging in one system. I had to label the Ethernet ports so I could hand over the hardware for certification and security scans.
So at this point I have my system running with a couple sensors setup with static IP's because I haven't had time to setup the DNS for the private network the sensors run on. Local IT goes to install McAfee and can't because it isn't compatible with anything after 1809 or later, I get a message back that " we only support up to 1709" I point out that it's server 2019, "Oh yeah, let me ask about that" a bunch of back and forth ensues and finally Local IT get's a version of McAfee that will install, runs security scan again i get a message back. " There are two high risk issues on your server", my blood pressure is getting high as well. The risks there looking at McAfee versions are out of date and windows Defender is disabled (because of McAfee).
There's a low risk issue as well, something relating to the DNS service I didn't fully setup. I tell local IT just disable it for now, then think we'll heck I'll remote in and do it. Nope can't remote into my server, oh they renamed it well that's lot going to stay that way but whatever oh here's the IP they assigned it, nope cant remote in no privileges. Ok so I run up three flights of stairs to local IT before they leave for the day log into my server yup RDP is enabled, odd but whatever let's delete the DNS role for now, nope you don't have admin privileges. Now I'm really getting displeased, I can;t have admin privileges on the network you want me to use to support the service on a system you can't support and I'm supposed to believe you can migrate the life safety systems you want us to move. I'm using my system to prove that the 2FA system works, at this rate I'm going to have 2FA access to a completely worthless broken system in a few years. good thing I rebuilt the whole server in a VM I'm planning to deploy before I get the official one back. I'm skipping a lot of the ridiculous back and forth conversations because the more I think about it the more irritated I get.1 -
Initially I was taking Network Security. Didn't like it that much. Figured I should explore and took a diploma in Information Tech.
First programming assignment, stayed up the whole night to solve it accompanied by a couple of Monster drinks. Got hooked on programming ever since. Picked up caffeine addiction along the way.
Oh and I'm now lactose intolerant. Strongly believe it's due to the large amounts of coffee I had back in the day. -
Firstly give me the skill equivalent to the best in the field. If the rules allow it all of these skills listed and if not any of these :-
1. Computer networking to the point of having the same knowledge as the best in the field. Why? I am curious about that stuff and being able to work as a network engineer if I don't get a good Dev job
2. Cyber security. Why? I enjoy it and being able to make sure my code is not easily exploitable is a cherry on top. Also having a backup job in case I don't get a good dev job
3. Being able to communicate with non dev people about developer or non developer stuff easily and being a really good leader.
4. Being a good developer in whatever language I use and instantly being able to learn new programming languages and frameworks or libraries with ultra in depth information. -
Why in the fuck does everyone expose specific ports in Dockerfiles?
If I wanted to expose the port, I would fucking expose it.
Currently can't run my home infra platform because I'm running two separate instances of Maria DB on the same private internal network. These are two databases for two separate applications.
Why don't I run them on one? Because they're two separate fucking applications.
Why the fuck can I not do this when I used to be able to do it a week ago.
Stop exposing your fucking ports in your fucking Dockerfiles.
This shit is getting so bad, I'm just about to throw my towel in on all fucking containers and just install everything in multiple VM environments.
I am God damn appalled that after 8 years of using docker, core concepts like a port exposure is being leveraged as a way to somehow circumvent poor security practices.
You want a secure container environment? Expose your own goddamn ports.
Fuck you Maria DB, and fuck you docker.2 -
Im considering a career in security or network security but want to get some steps aheah, where should i look? What should i read?6
