So this is how my low numbered account was stolen back in the day - thanks for sharing.
Can’t believe I still remember my ICQ id
I read your comment and realized I also do haha lol lfmao rofl
Mine is seared into my brain. It's also cheating a bit because it's only six digits.
I was gonna drag you for making such a silly flex then I realized I'm just jealous because mine was eight
Mine was 7 but I had it fur 5 years.

I also remember my compuserve id which lasted a mere 6 months over 30 years ago, And that was 10 digits.

Same like my Geocities homepage, never forget.

I feel like it's the same with your first phone number back when there were only landlines, etc. Some numbers are hard-wired.

If it happened to me, my next move would be to steal it back
My UIN was merely 7-digit and when it got hacked the guy just logged in, chatted with my friends about random things, and left. I only found out because they were puzzled by "me" talking weird.
I wonder whether the password change mechanism asked for the old password... or if the same flaw existed.

"What's your old password?"

"something_more_than_8_characters_long"

"Let me check. The result of the check is... ERROR. Great, what's your new password?"

Rewrite it in Rust
Ask an agent to rewrite it in Rust. #ftfy
It'd be blazingly fast!
>When a password of 9 or more characters is sent, their buffer is over-run, and it allows you to log in.

Man, computers used to be fun

Yep, now everything is done through agents unfortunately.
Unix crypt only accepted 8 characters and ignored the rest. If your password was 123456789, it was considered the same as 12345678a.
For local LAN play, Half-Life checked the CD key only for length I believe? It would happily accept 1234-56789-0123
I remember when ICQ used to give you the other persons IP address.

Then you could use that to winnuke them.

today you can use a WhatsApp call. or meet/teams/zoom...
Lucky for me, my ICQ password was only 8 characters. And I used it on every website!

(To this day I can recall my ICQ number faster than my childhood phone number or my social security number.)

I often half-joke that my ICQ number is the last thing I'll forget if I get Alzheimer, long after my own name.
Mine is still burned into my brain but I managed to get locked out a couple of decades ago so can't even do a nostalgia login.
8? That was fancy. Mine was 7, all lower case characters, and I also used it on every website!
This made me almost spit out my coffee in laughter. This just made my day, hahaha
I seem to vaguely recall some buffer overflow for Sun Solaris, which was fun to login with. I do wonder what fun AI would have had crawling through these old code bases to find the crazy exploits available back then
BCrypt also comes to mind, as a more recent example ...
Uh oh!
Incoming file transfer
Oh god this instantly took me back to my the way teenage years' room felt and smelled.
like hamsters
There are some point of sales systems that use the same sound effect, and every time it's like I'm teleported back to the 90s, sitting in my room with a pepsi, browsing the web and chattin' with friends.
I only recall this beibeing used by McDonald’s in Russia, which seems to check out (no pun intended) considering your username :-)
Hah! I haven't been to a Russian McDonald's in ... certainly over a decade, maybe longer.

AOL Instant Messenger had several remote code execution exploits. They worked just by sending an IM to someone. You could also crash their computer remotely, or maybe it would just create their client.

Also their stored password encryption algorithm was easily reversible.

The AIM days are one for the books. What a time to be alive and interested in computerin'
Wasn’t that how audio avatars worked (not by crashing, but ACr)? What a time to be alive.
Don't know how they worked, but what you did to create one was rename a .wav to a .jpg .gif .bmp .etc
AIM's built-in HTML parser had a bunch of super-linear parser complexity bugs, leading to people building "punters".
This made me realize that I still remember my ICQ UIN! I cannot remember what I've had for lunch yesterday, btw.
Mine began with a 2. Just saying.
That matters not at all, unless you reveal how many digits it is. Why isn’t anyone in this thread willing to reveal theirs? Just brag about it?

Mine also began with a 2. It was 279866. My girlfriend’s was slightly lower, as she introduced me to the new service. We both felt like pioneers in those halcyon days.

Mine was quickly usurped by a Russian hacker. The profile was replaced by Cyrillic writing. I never knew how they did it. None of my other accounts or socials have ever been usurped like that!

More importantly: Are you and your girlfriend still in contact with each other today?
In my case because I use it as a random seed or parts of it as PIN, cause I will never forget it and it's "secret" enough.
I remember a lot of low number ICQ accounts being taken over back in the day, including my own and several security-minded friends. Because of how prevalent it was and how it was the only account we'd had compromised we assumed they found a flaw or had access to reset passwords, or could social engineer support etc.

It's good to finally know there was a critical flaw like the one in OP that was likely used.

Mine was 8966646, which is cool because it has 666 in it.
Mine was in the 3.5 million range. My roommate at the time had a 6 digit number and didn't sign up that much before me, I remember it felt wild that they had grown so quickly. And then not long after that it was all 8 digit numbers.

And also yes, the last time I looked, my account was all cyrillic.

2726304

I forgot my ATM PIN though.

I think I discovered that by mistake using Miranda client in 2002!

The tech scene of the 90s in Israel was crazy. Mirablis was hiring high school students to do QA.

> Mirabilis / AOL really needs to fix this problem.
ICQ sent messages directly between peers when both were online and unfirewalled and there were no verification that you were who you claimed. I had a lot of (friendly) fun spoofing other ICQ numbers. Or sending someone a message from themselves.
i still remember my ICQ number all these years later.
AI is really a dangerous technology, look how fast it’s discovering major security flaws!
Am I correctly understanding that ICQ had an 8 character limit on the passwords?
So this is a buffer overflow on the server side! Could probably have been used for RCE on their infrastructure. No NX, no ASLR, etc. of course it would be difficult to work it blindly without the binary or some sort of info leak.
