More Information

W32/Sdbot-AGJ is a network worm with backdoor Trojan functionality for the Windows platform.

When first run W32/Sdbot-AGJ copies itself to:

\eminem vs 2pac.scr

The following registry entries are created to run mssnt.exe on startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Microsoft Windows MSNNT
mssnt.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Microsoft Windows MSNNT
mssnt.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Windows MSNNT
mssnt.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Windows MSNNT
mssnt.exe

Registry entries are set as follows:

HKCU\SYSTEM\CurrentControlSet\Control\Lsa
Microsoft Windows MSNNT
mssnt.exe

HKLM\SYSTEM\CurrentControlSet\Control\Lsa
Microsoft Windows MSNNT
mssnt.exe

HKCU\Software\Microsoft\OLE
Microsoft Windows MSNNT
mssnt.exe

HKLM\SOFTWARE\Microsoft\Ole
Microsoft Windows MSNNT

The worm spreads through network shares protected by weak passwords, MS-SQL servers and through various operating system vulnerabilities including: LSASS (MS04-011), RPC-DCOM (MS04-012) and ASN.1 (MS04-007).

W32/Sdbot-AGJ connects to a predetermined IRC channel and awaits further commands from remote users.
