W32/Sdbot-KW 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-KW 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-KW copies itself to the Windows System folder as IEXPLORE.EXE and creates entries in the registry at the following locations to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Configuration Loader = IEXPLORE.EXE
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Configuration Loader = IEXPLORE.EXE
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Configuration Loader = IEXPLORE.EXE
W32/Sdbot-KW can delete shared network drives and collect CD keys from several popular computer games and applications.
