Summary: Trojan. A program that appears to do one thing but actually does another (a.k.a. Trojan Horse).
Dynamic Analysis
Payload
Behaviour | Description |
---|---|
WormAutorun | A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Trojan's file once a user opens a drive's folder in Windows Explorer. |
IRCBot | A bot can communicate with command and control servers via IRC channel. |
MSNWorm | A worm can spread its copies through the MSN Messanger. |
Trojan-Proxy | This program can launch a proxy server (SOCKS4) on a designated TCP port. |
