More Information

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

W32/Rbot-ATA spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), WKS (MS03-049) (CAN-2003-0812) and ASN.1 (MS04-007).

W32/Rbot-ATA 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-ATA copies itself to <System>\MSAOL32dll.exe.

The following registry entries are created to run MSAOL32dll.exe on startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
AOL Instant Messenger dll runtime
MSAOL32dll.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
AOL Instant Messenger dll runtime
MSAOL32dll.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
AOL Instant Messenger dll runtime
MSAOL32dll.exe
