31337 is just an example port! aMSN is binding an ephermal port after you've started it. Just do a netstat -an and look for ephermal ports. If you get the aMSN port you can connect to it and sending some characters and you'll get replies by aMSN. If you send an '{' or '}' character to that amsn port, you'll notice that aMSN is reporting an error message (amsn window). But if you going to send more than one character of '}' or '{' it will be killed. Yes, the whole client! To "Ismail Soenmez":
Learn to spell my name correctly first.
What about "DDoS"? Sending characters to that port in an "infinite" loop is a DDoS for you?
If you read the PoC you wrote you'll see that you forgot to increment the value of i in the loop. So yes you are sending packages in an infinite loop. Thats DoS, never mind the double D I stuck up there. -- Life is a game, and if you aren't in it to win, what the heck are you still doing here? -- Linus Torvalds (talking about open source development)
