More Information
W32/Sdbot-BPZ is a network worm with backdoor Trojan functionality for the Windows platform.
When first run, W32/Sdbot-BPZ copies itself to the Windows folder as winsmc.exe and creates the following registry entry in order to run each time a user logs on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
WinScMngr
"<Windows folder>\winsmc.exe"
The worm spreads through network shares protected by weak passwords, MS-SQL servers and through various operating system vulnerabilities.
W32/Sdbot-BPZ also drops a file as rdriv.sys. Sophos's anti-virus products detect rdriv.sys as Troj/Rootkit-W.
W32/Sdbot-BPZ connects to a predetermined IRC channel and awaits further commands from remote users. The backdoor component of W32/Sdbot-BPZ can be instructed to perform the following functions:
scan networks for vulnerabilities
download/execute arbitrary files
start an ftp server
