An incident which made a Security Researcher cry
I was working on my laptop finishing up my code while waiting for the flight which was late . Meanwhile two guys (I'm gonna call them Fellas) in black suit and shades came to me
Fella : Sir you have to come with us .
Me : *goes along with them*
Fella : Sir please proceed *points towards the door . The room has a round table with some guys discussing something *
Fella 1 : Your passport please
Me : *Hands over the passport*
Fella 1 : Where are you traveling to sir?
Me : India
Fella 1 : Put your laptop in the desk sir.
Me : Sure thing
Fella 2 : What were you doing there? *Taps the power button*
Me : Just finishing up my work .
Fella 1 : Or hacking our systems?
Me : Seriously?
Fella 2 : The password please .
Me : Here you go
*5 minutes have passed and he still can't figure out how to use the machine*
Fella 2 : Which Windows is this?
Me : It's Linux
Fella 1 : So you are a hacker .
Me : Nope
Fella 1 : You are using Linux
Me : Does it matters?
Fella 1 : Where do you work?
Me : *I won't mention here but I told him*
Fella 2 : So what do you do there?
Me : I'm a Security Researcher
Fella 1 : What's your work?
Me : I find security holes in their systems .
Fella 1 : That means you are a hacker .
Me : Not at all .
Fella 2 : But they do the same and they use Linux .
Me : You can call me one .
*After 15 minutes of doo-laa-baa-dee-doo-ra-ba-doo amongst them I dunno what they were talking , they shutdown the computer and handed over it to me*
Fella 2 - So you are somewhat like a hacker .
Me - *A bit frustrated* Yes.
##And now the glorious question appeared like an angel from river ##
Can you hack Facebook?
Me - 😭😭😭32

So What should i do?
i thought of making a crawler and then make statistics on everyones orders and send Them a link 😂20
Context: I work in a cyber security company which develop cyber security solutions.
I started testing the API of the dashboard we have. Within 15 minutes, after poking around with burp suite, found SQL injection in post data that leads to the whole DB dumping in sqlmap.
Told the boss and the API developer. Boss said, "it's ok to have bugs/holes in trial box". But this is on a machine that is gonna be sent to client for trial in a few days. I even compiled a report and how to fix it, which is like 2 lines of "if else" statement by the way. Told the API developer how to fix, he didn't care. 'I work on functionality first'. Doesn't look like he gonna fix.
A damn cyber security company, developing cyber security solution, do the "don't" in web security 101, which is dumping POST data directly into the SQL query, which requires only 5 minutes to fix. 🤦♂️🤦♂️🤦♂️15
Yesterday my father called me and asked if I'd have a look at his website to exchange his logo with a new one and make some string changes in the backend. Well, of course I did and hell am I glad I did it.
He had that page made a few years ago by some cousin of a friend who "is really good with computers", it's a small web shop for car parts and, as usual costumer accounts. Costumer Accounts with payment infos.
Now I've seen a lot of bad practices when it comes to handling passwords and I've surely done a few questionable things myself but this idiot took the cake. When a new account was registered his php script would read the login page, look for a specific comment and add a string "'account; password'," below into to a js array. In clear text. On the website. One doesn't even have to breach the db, it's just there, F12 and you got all the log ins.
Seriously, we really need a licensing system for devs, those were two or three years this shit was live, 53 accounts... Now I've gotta decipher this entire bowl of spaghetti just to see if he has done any more unspeakable things.4
Sometimes I wonder how compromised my parents online security would be without my intervention.
My mom logged into her gmail and there was an red bar on top informing about Google preventing an attempted login from an unknown device.
Like typical parents / old people, that red bar didn't caught her attention but I noticed it immediately. I took over and looked into it. It showed an IP address and a location that was quite odd.
I went ahead with the Account security review and I was shocked to find that she had set her work email address as the recovery email!!
I explained her that work email accounts cannot be trusted and IT department of the workplace can easily snoop emails and other info on that email address and should not be related to personal accounts.
After fixing that issue, me being a typical skeptic and curious guy, I decided to find more info about that IP address.
I looked up the IP address on a lookup website and it showed an ISP that was related to the corporate office of her workplace. I noticed the location Google reported also matched with the corporate office location of her work.
Prior to this event, few days ago, I had made her change her gmail account password to a more secure one. ( Her previous password was her name followed by birth date!! ). This must have sent a notification to the recovery mail address.
All these events are connected. It is very obvious that someone at corporate office goes through employees email addresses and maybe even abuse those information.
My initial skeptism of someone snooping throguh work email addresses was right.
You're welcome mom!9
We recently took over development of an app. Upon inspection the API had no security, and passwords were stored in plain text. While the manager was slightly concerned, it wasn't a big deal....
That was until, using only a browser, I found the bosses account and personal email address.
Minutes later I was in his gmail, Facebook and credit cards account.
Improving security is now concern #1, and my boss is "suffering" 2 factor authy on everything.7
Client: why do I have to use such a hard password for this website?
Me: For security reasons to protect your content and identity of your clients.
Client: Can't you just use the password that I'm used to? I use it on my banking software, and I've never been hacked so it should be good enough for you!
Me: what's the password that you want me to set up for you?
Client: you ready to take it down?
Me: go ahead.
Client: T ... U ... R ... D. You got that?
Me: ... Yes ...
Recently, one of our passwords was accidently published on a public page for a few minutes before it was noticed and removed. Unfortunately, this password opens nearly every locked account so it's a pretty big deal.
Management was informed of this mistake and told that we should change the passwords as well as implement a few other protocols to make sure this doesn't happen again including things like unique passwords, more secure passwords, using a password manager, etc.
Their response? It wasn't online long, probably no one saw it. There will be no changes in how we handle ours or our clients' secure passwords.6
Pro security tip:
Use a very simple password because h4x0rs expect a difficult one so they can't cr4ck yours9
A friend of mine got an account hacked on Crunchyroll. Whenever he tried to login, the website told him that no account with his email existed. As I had two accounts, I tried something real quick. I logged in to the account I'm not using and tried to change the email address to a 10 minute mail. I logged into my own email account patiently waiting for a confirmation email. After 10 minutes I still hadn't received it. So I checked the 10 minute mail, and there it was. I can't describe how furious I got with Crunchyroll at that point. Are you for real? It's that easy? Fucking idiots. I hope the guy responsible for that system dies in a fire with a thousand rubber penises up his ass!8

Microsoft seriously hates security, first they do enforce an numer, upper and lowercase combined with a special character.
But then they allow no passwords longer than 16 characters....
After that they complain that "FuckMicrosoft!1" is a password they've seen to often, gee thanks for the brute force tips.
To add insult to injury the first displayed "tip" take a look at the attached image.16
Our main server that stores everything and that everyone uses has been down for about an hour now. It's okay though I get paid by the hour. Plus, I'm working remotely today.
Probably doesn't help that we let other people other than the IT department mess with what we put on the server.1
You can fuck right off.
First it won't let me have two of the same characters consectively, which fine, technically makes a more secure password.
But then blocks more than 12 characters?
TIL if you know the password for a WIFi SSID, you can replicate it with your hardware. All devices that have credentials for that SSID will connect to yours if your signal is stronger. The encryption just needs to be the same (wpa2/wep) The underlying UUID doesn’t matter.
Not bad for a quick and dirty man-in-the-middle attack. The WiFi spec needs a bit more work.
TLS all the things!4
I saved passwords to db hashed to SHA-1 with no salt... I left that company but I'm sure that application is still actively used today.2
We are going to start accepting credit cards again. Old boss wants to store the tokens in plain text work the last 4 digits of the credit card...5
I think I have figured out a way of making memorable and secure passwords...
Look through your old code and pick the cringiest, the worst snippets of code you can find, and use them as your passwords7
So it's required by law to chip and register your dog. I just got a puppy so I had to change the owner of the dog from the kennel to me. And the only thing I needed was my chipvalue and the registration number.
So all I have to do is scan the dog and try the registration numbers and then I can change the owner. Like wtf. And it does not even send a confirmation email. I checked by changing owner and email again.
My registration number is only in the 600K so other registered pets should be easy enough to bruteforce.
Or am I missing something?8
A conversation between an offshore developer and his manager at a fortune 500:
I'm a software developer and the company I work for is a vendor for $manager's and $offshore_dev's company. They provide endless hours of entertainment/terror. Recently, we've been trying to convince them that they need to stop sending sensitive information plaintext over HTTP and set up TLS/HTTPS which has led to tons of fun conversations such as this one they had during a conference call:
* $manager: "Did $offshore_dev implement TLS1.2?"
* $offshore_dev: "Yes, we enabled a parameter in the code to enable TLS1.2 in the code but according to $me's email, this requires HTTPS in order to work."
* $manager: "No this works, we're using TLS in $other_application right now."
* $offshore_dev: "Well, $manager, it's implemented but it currently doesn't encrypt anything as such."
* $manager: "Okay, HTTPS is in the roadmap in the next quarter, we can move forward without this for now."4
I save all my work relate passwords in a single text file on my computer. I always have it open too.
Too many systems, too many password requirements, expires too frequently.1
airBaltic: hey, mister hacker, so these are characters our users can use for their password, we made everything to ensure the best hacking experience for you.
What’s the other fucking reason for doing it? Are they storing passwords in plain text, so it’s some weird kind of escaping technique?
Forbidding characters in passwords means only single thing for me, I can’t trust company’s competence of keeping my personal data.8
Having a meeting with an old client of our company's today, guiding him through the deployment process for his front and backend, because he thought that we were withholding information, and at one point in the call he asks me if the './' at the beginning of the deployment script was a special security measure put in place by us... 😂
Anyone else hates the "Getting started" docs as much as I am?
Problem is, most of the code is only useful for doing exactly this - "start a totally useless chat between two windows" for example for Broadcast in Laravel. What is missing is the part where you need to auth with an API in the backend and because it is missing, we see giant security holes in websites that are basically made from 101 tutorials...
Me and other dev discussing how to easily get stacktraces during UAT
Other: Wont it be better if the users can send us the stacktraces themselves?
Me: No, we have to catch unhandled exceptions and just display a generic message to avoid accidentally dumping sensitive info to the client.
Other: Okay, let's just do console.log() instead

When your redirect url passed as get parameter to 'secure' the login you pass bade64 envoded string with path, length and (salted) md5 hash ....
why God why you secure a redirect you do 302 to on success1
I've been working for so long with API integrations and one part of that is security. We perform ssl key exchanges for 2-way verification and a large percent of those partners provides me with their own pkcs12 file which contains their private and public keys! What's the sense of the exchange!? I think they just implement it just to boast that they "know" how ssl works,
Is there an encryption/decryption algorithm that's guaranteed to have an output of less than 100 chars? Say to encrypt messages less than 50 chars in length5
