Determining a computer's OS?

I've seen little message board signature thingies that display the OS and (proxy) IP addresses of whoever's browsing that webpage. I figured that it was some sort of javascript function or other, but then recently I was talking to a script kiddie over aim, and he correctly told me my OS while rattling on about how 1337 he was. I wasn't directly connected with him, and I never gave him my IP address either.

So, my question is how can anyone figure out my OS like that? Any replies would be appreciated.

Did you recieve or send him a file, or photo, or anything. In other words did you have a direct contection to him at anytime, or was it just through AIM chat function?

Is this what your talking about? http://www.neg.be/php/checker.php

As for this dude knowing your OS and other stuff ...maybe you have a trojan on your box.
That would explain how he knows this. Who knows that`s just a thought.

I wasn't directly connected (I already mentioned this!), and I don't have any trojans on my computer... as far as I know :]

You do now =D

How detailed did he or she get? If I add you to my buddy list, I can easily make an assumption of what OS you have just by putting the mouse arrow over your name, and it shows what capabilities you have. The capabilities can pretty much point at what you're running.

There is a shitload of info here on exactly what your asking if you just search and read.

I didn't know that, but I don't use AIM either.

Dosent that really just give you a hint as to if they have dial up or broadband?
I mean the items listed under capabilities

I mean it`s a 90% chance they are running windows anyway....right?

Na, you can do more than that.

For example, I have Gaim signed on right now on this box:

Capabilities: Chat, send file

My cousin's machine running Gaim:

Chat, Send File, Direct IM, buddy icon.

A buddy on my list running Windows:

Buddy Icon, Voice, Direct IM, chat, send file, add ins, send buddy list,
IChat, AV

AIM for Linux is what I have on the bext next to me, the capabilities are:

Chat, Send file.


See the difference? Windows version has more. :)

I am a creative bastard though ;)

Ahh quit stroking yourself, big boy. We all know how smart you are.... and your good taste in music.

hehehe

Misfits rule!!

Sorry for the interruption, now back to your regularly scheduled B.S.

I dont know that much , but chances are youre running windows.....like most of everyone on the web...and if they're just a "script kiddie', chances are theyre running windows too ;-)

am by sending file over iaim other user can get your ip address through dos command line typing netstat may display your ip during transfer of file or sendaing data maybe that y he got yoour ip and scan your computer, or using ftp they can look for your ip address and the OS hope this info help a little bit

I think he's referring to this website

ydobon -
I know exactly what you are talking about with the "message board thingies". The link that Ms. Mittens provided has the same type of message board (only with a different character) that I've seen used by an AntiOnline user when they are posting to a thread here. I tried to find one of their posts . . . but since I was looking for one . . . I couldn't find one to save my life (Murphy's law).

I've often wondered myself how this is accomplished. Maybe someone will actually answer your question . . . or provide a link for reference . . . then we'll both know. Good luck in your quest!

These links might provide some insight into the how. The 2nd one shows how they created their "own" variation.

I thought there was a way to find out what OS you are running? Well when you go to a web site that requires you to be running a OS like windows, can't you tell that person go there and that will be one way to find out. But also if you need to load any Java or script on a computer don't the web site need to know what OS you are running? I know this is off the subject but I just think there got to be a way to find out!

He could've probably sent him to a website which logged his OS, or somehow, got his IP and found out his TTL. or as was later mentioned a trojan could've been installed.
