Hack PC while Chatting

I am not sure that this will work 100%. But yes will work almost 70 percent of the times. But before that you need to know some few things of yahoo chat protocol... Following are the features : - 1) When we chat on yahoo every thing goes through the server. Only when we chat thats messages. 2) When we send files yahoo has two options- a) Either it uploads the file and then the other client has to download it. b) Either it connects to the client directly and gets the files. 3) When we use video or audio:- a) It either goes through the server Or it has client to client connection And when we have client to client connection the opponents IP is revealed. On the 5051 port. So how do we exploit the Chat user when he gets a direct connection. And how do we go about it. Remember I am here to hack a system without using a TOOL only by simple net commands and yahoo chat techniques. Thats what makes a difference between a real hacker and newbees. So lets analyse 1) Its impossible to get a Attackers IP address when you only chat. 2) There are 50% chances of getting a IP address when you send files 3) Again 50% chances of getting IP when you use video or audio. So why to wait lets exploit those 50% chances . I'll explain only for files here which lies same for Video or audio 1) Go to dos type -> netstat -n 3 You will get the following output. Just do not care and be cool... Active Connections Proto Local Address Foreign Address State TCP 194.30.209.15:1631 194.30.209.20:5900 ESTABLISHED TCP 194.30.209.15:2736 216.136.224.214:5050 ESTABLISHED TCP 194.30.209.15:2750 64.4.13.85:1863 ESTABLISHED TCP 194.30.209.15:2864 64.4.12.200:1863 ESTABLISHED Active Connections Proto Local Address Foreign Address State TCP 194.30.209.15:1631 194.30.209.20:5900 ESTABLISHED TCP 194.30.209.15:2736 216.136.224.214:5050 ESTABLISHED TCP 194.30.209.15:2750 64.4.13.85:1863 ESTABLISHED TCP 194.30.209.15:2864 64.4.12.200:1863 ESTABLISHED Just i will explain what the out put is in general.In left hand side is your IP address.And in right hand side is the IP address of the foreign machine.And the port to which is connected.Ok now so what next -> 2) Try sending a file to the Target. If the files comes from server, thats the file is uploaded leave it. You will not get the ip. But if a direct connection is established hmmmmmm then the first attacker first phase is over This is the output in your netstat. The 5101 number port is where the Attacker is connected. Active Connections Proto Local Address Foreign Address State TCP 194.30.209.15:1631 194.30.209.20:5900 ESTABLISHED TCP 194.30.209.15:2736 216.136.224.214:5050 ESTABLISHED TCP 194.30.209.15:2750 64.4.13.85:1863 ESTABLISHED TCP 194.30.209.15:2864 64.4.12.200:1863 ESTABLISHED TCP 194.30.209.15:5101 194.30.209.14:3290 ESTABLISHED 3) so what next??? Hmmm........ Ok so make a DOS attack now Go to dos prompt and Just do nbtstat -A Attackers IPaddress. Can happen that if system is not protected then you can see the whole network. C:\>nbtstat -A 194.30.209.14 Local Area Connection: Node IpAddress: [194.30.209.15] Scope Id: [] NetBIOS Remote Machine Name Table Name Type Status --------------------------------------------- EDP12 <00> UNIQUE Registered XYZ <00> GROUP Registered XYZ <20> UNIQUE Registered XYZCOMP1 <1e> GROUP Registered MAC Address = 00-C0-W0-D5-EF-9A What to do next?? It is now your job to tell me what you have done next... So the conclusion is- never exchange files, video or audio till you know that the user with whom you are chatting is not going to harm you.
