More Information

W32/Sdbot-QI is a worm that attempts to spread via remote network shares. The worm tries to access various network computers with shared folders using weak passwords.

W32/Sdbot-QI contains backdoor Trojan functions that allows unauthorised remote access to the infected computer via IRC channels while running in the background.

When run W32/Sdbot-QI copies itself to the Windows system folder as win.exe.

The worm also creates the following registry entries so that it is able to run on user logon or computer startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Remote Procedure Calls = win.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Remote Procedure Calls = win.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Remote Procedure Calls = win.exe

W32/Sdbot-QI may also attempt to change the following registry entries:

HKLM\Software\Microsoft\OLE
EnableDCOM = N

W32/Sdbot-QI will attempt to delete network shares, partake in DoS attacks, steal computer information, download and run files from the Internet when instructed to do so by a remote attacker.
