More Information

W32/Rbot-BBE is a worm and IRC backdoor Trojan for the Windows platform.

W32/Rbot-BBE spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: RPC-DCOM (MS04-012), PNP (MS05-039) and ASN.1 (MS04-007).

W32/Rbot-BBE runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.

When first run W32/Rbot-BBE copies itself to <System>\svchoste.exe.
