More Information

W32/Agobot-VE is a worm with backdoor functionality for the Windows platform.

W32/Agobot-VE spreads:

- to other network computers infected with: W32/Sasser and Troj/Optix
- to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), WebDav (MS03-007), UPNP (MS01-059) and Dameware (CAN-2003-1030)
- by copying itself to network shares protected by weak passwords

W32/Agobot-VE 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/Agobot-VE copies itself to <Windows system folder>\animalss.exe.

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

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
animalss
animalss.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
animalss
animalss.exe
