More Information

W32/Agobot-UJ is a worm and IRC backdoor Trojan for the Windows platform.

W32/Agobot-UJ spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812) and WebDav (MS03-007) and by copying itself to network shares protected by weak passwords.
