More Information
W32/Sdbot-JS 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-JS drops two files to the folder C:\WinNT\system32. One is dropped as GFHHR.EXE and is also detected as W32/Sdbot-JS, the other is dropped as KHJBB.EXE and is detected as Troj/Ranck-X.
The file dropped as GFHHR.EXE copies itself to a file called BNDSDX.EXE in the Windows system folder and creates entries in the registry at the following locations to run this copy on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
W32/Sdbot-JS spreads to network shares with weak passwords as a result of the backdoor Trojan element receiving the appropriate command from a remote user, spreading by copying the file GRGWIT.EXE from the Windows system folder (which should be the original W32/Sdbot-JS dropper file) to the remote computer.
