W32/Sdbot-KZ is a worm which attempts to spread to remote network shares. It also contains backdoor Trojan functionality, allowing unauthorised remote access to the infected computer via IRC channels while running in the background as a service process.

W32/Sdbot-KZ spreads to network shares with weak passwords as a result of the backdoor Trojan element receiving the appropriate command from a remote user.

W32/Sdbot-KZ copies itself to the Windows System folder as XXX.EXE and creates the following entries in the registry to run itself on system startup:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Synchronization Manager = xXx.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Microsoft Synchronization Manager = xXx.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Synchronization Manager = xXx.exe

W32/Sdbot-KZ can delete shared network drives and collect CD keys from several popular computer games and applications. This worm may also log the users keystrokes into a file in the Windows System folder named KEYLOG.TXT.
