More Information
W32/Agobot-DD is an IRC backdoor Trojan and network worm. W32/Agobot-DD is capable of spreading to computers on the local network protected by weak passwords. When first run, W32/Agobot-DD moves itself to the Windows system folder as s3serv.exe and creates the following registry entries to run itself automatically on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\ Run\S3 Internal Chip = s3serv.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\ RunServices\S3 Internal Chip = s3serv.exe
On NT based versions of Windows the worm creates a new service named "S3 Internal Chip" with the startup property set to automatic, so that the service starts automatically each time Windows is started. Each time W32/Agobot-DD is run it attempts to connect to a remote IRC server and join a specific channel. W32/Agobot-DD then runs continuously in the background, allowing a remote intruder to access and control the computer via IRC channels. W32/Agobot-DD attempts to terminate and disable various security related programs and attempts to prevent its own process from being deleted.
