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 :P

So I've been looking for a Linux sysadmin job for a while now. I get a lot of rejections daily and I don't mind that because they can give me feedback as for what I am doing wrong. But do you know what really FUCKING grinds my FUCKING gears?

BEING REJECTED BASED ON LEVEL OF EDUCATION/NOT HAVING CERTIFICATIONS FOR CERTAIN STUFF. Yes, I get that you can't blindly hire anyone and that you have to filter people out but at least LOOK AT THEIR FUCKING SKILLSET.

I did MBO level (the highest sub level though) as study which is considered to be the lowest education level in my country. lowest education level meaning that it's mostly focused on learning through doing things rather than just learning theory.

Why the actual FUCK is that, for some fucking reason, supposed to be a 'lower level' than HBO or Uni? (low to high in my country: MBO, HBO, Uni). Just because I learn better by doing shit instead of solely focusing on the theory and not doing much else does NOT FUCKING MEAN THAT I AM DUMBER OR LESS EDUCATED ON A SUBJECT.

So in the last couple of months, I've literally had rejections with reasons like
- 'Sorry but we require HBO level as people with this level can analyze stuff better in general which is required for this job.'. - Well then go fuck yourself. Just because I have a lower level of education doesn't FUCKING mean that I can't analyze shit at a 'lower level' than people who've done HBO.

- 'You don't seem to have a certificate for linux server management so it's a no go, sorry!' - Kindly go FUCK yourself. Give me a couple of barebones Debian servers and let me install a whole setup including load balancers, proxies if fucking neccesary, firewalls, web servers, FUCKING Samba servers, YOU FUCKING NAME IT. YES, I CAN DO THAT BUT SOLELY BECAUSE I DON'T HAVE THAT FUCKING CERTIFICATE APPEARANTLY MEANS THAT I AM TOO INCOMPETENT TO DO THAT?! Yes. I get that you have to filter shit but GUESS WHAT. IT'S RIGHT THERE IN MY FUCKING RESUME.

- 'Sorry but due to this role being related to cyber security, we can't hire anyone lower than HBO.' - OH SO YOUR LEVEL OF EDUCATION DEFINES HOW GOOD YOU ARE/CAN BE AT CYBER SECURITY RELATED STUFF? ARE YOU MOTHERFUCKING RETARDED? I HAVE BEEN DOING SHIT RELATED TO CYBER SECURITY SINCE I WAS 14-15 FUCKiNG YEARS OLD. I AM FAMILIAR WITH LOADS OF TOOLS/HACKING TECHNIQUES/PENTESTING/DEFENSIVE/OFFENSIVE SECURITY AND SO ON AND YOU ARE TELLING ME THAT I NEED A HIGHER LEVEL OF FUCKING EDUCATION?!?!? GO FUCKING FUCK YOURSELF.

And I can go on like this for a while. I wish some companies I come across would actually look at skills instead of (only) study levels and certifications. Those other companies can go FUCK THEMSELVES.

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?

Security!

Offensive and defensive at both code and infrastructure levels.

So many times I see devs not give a flying pancake about security. Whether it be rolling integers for sql injection or permission guarding to prevent someone executing something they shouldn't.

Why is security in this industry always the last thing to be concerned about when it's the first thing that's going to kill your business.

😓

Legitimately thinking about having everyone in my department take the ejpt certification test followed by the Offensive Security examination, just because I think those are some legitimate skills to have for devs.

where is offensive security actually being taught? i know for a fact it is not at any university because universities only teach technology that is over 20 years old. they dont give a fuck to learn something new. so, if i wanted to learn that, where do i go?

Does printing in the terminal "go hack yourself" in each session counts as offensive security ?

How many people on devRant are skilled with pentesting / Offensive Security? How long did it take you to understand it? How do you keep yourself from crossing over white hat territory into grey hat territory?

I just signed up for the preparation course for the Offensive Security Certified Professional (OSCP) certificate. Does anybody have experience doing this course? or has maybe some tips for the exam? or any learning suggestions?
I‘ve decided not to get a CEH certificate because its just too theoretical, the OSCP is way more practical and i think there is way more to learn from this course/exam

Whatever be the current trend on Linked-In, at the end of the day the product development life cycle remains quite the same.

Still, as developers which general domains in software do you think would flourish in the near future?

My picks (not in order) -
>> Cyber security : automation, both offensive and defensive
>> Block chain : trustable data platforms
>> Applied AI : a few key models, applied to all niches, bettering existing UX
>> IOT : wearables, embeddables, smart appliances
>> AR : Navigation prompts, real time info about real life objects
>> VR : Immerse entertainment. (Metaverse 🤮)
>> Quantum computing : first gen costly commercial releases, new algos

What would you add or subtract from this?
