More Information

W32/Rbot-AUI is a worm and IRC backdoor Trojan for the Windows platform.

W32/Rbot-AUI spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012) and WKS (MS03-049) (CAN-2003-0812) and by copying itself to network shares protected by weak passwords.

W32/Rbot-AUI 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/Rbot-AUI copies itself to <System>\jorgf.exe.

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

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Launch Norton AntiVirus 2000
jorgf.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Launch Norton AntiVirus 2000
jorgf.exe

The following registry entry is set:

HKCU\Software\Microsoft\OLE
Launch Norton AntiVirus 2000
jorgf.exe
