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

W32/Rbot-ATP spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: RPC-DCOM (MS04-012) and PNP (MS05-039) and by copying itself to network shares protected by weak passwords.

W32/Rbot-ATP 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-ATP copies itself to <System>\firefox.exe.
