W32/Sdbot-AGP is a worm and IRC backdoor Trojan for the Windows platform.
W32/Sdbot-AGP 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.
W32/Sdbot-AGP attempts to spread by exploiting the following vulnerabilities:
LSASS (MS04-011), RPC-DCOM (MS04-012) and ASN.1 (MS04-007). The worm may also spread to remote network shares with weak passwords.
When first run W32/Sdbot-AGP copies itself to <System>\videodrv.exe.
