W32/Sdbot-AEG is a worm and IRC backdoor Trojan for the Windows platform.
W32/Sdbot-AEG may attempt to send itself via AOL Instant Messenger.
W32/Sdbot-AEG 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.
When first run W32/Sdbot-AEG copies itself to <System>\lockx.exe and creates the following files:
msdirectx.sys
xz.bat
The file xz.bat is detected as Troj/KillProc-A and the file msdirectx.sys is detected as Troj/NtRootK-F.
The following registry entries are created to run lockx.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
stratas
lockx.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
stratas
lockx.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
