More Information
W32/Sdbot-DIW is a worm for the Windows platform.
W32/Sdbot-DIW 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-DIW includes functionality to access the internet and communicate with a remote server via HTTP.
When first run W32/Sdbot-DIW copies itself to:
<Windows>\ccSvcHst.exe
<Program Files>\KaZaA\My Shared Folder\<random file name>.exe
and creates the file <Windows>\Dance_dec_jpg.zip.
W32/Sdbot-DIW modifies the following files, affecting the system file checker and command line file transfers:
<System>\sfc_os.dll
<System>\ftp.exe
<System>\tftp.exe
These files should be restored from a clean system backup.
W32/Sdbot-DIW may create the files:
<System>\backup.ftp
<System>\backup.tftp
which are the original copies of ftp.exe and tftp.exe.
The following registry entry is created to run ccSvcHst.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
ccSvcHst.exe
<Windows>\ccSvcHst.exe
Registry entries are set as follows:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
