More Information
W32/Rbot-AVI is a worm with IRC backdoor functionality for the Windows platform.
W32/Rbot-AVI spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), WKS (MS05-012), WKS (MS03-049) (CAN-2003-0812), PNP (MS05-039) and by copying itself to network shares protected by weak passwords.
The following patches for the operating system vulnerabilities exploited by W32/Rbot-AVI can be obtained from the Microsoft website:
MS04-011
MS05-012
MS03-049
MS05-039
W32/Rbot-AVI 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-AVI copies itself to <Windows system folder>\packe.pif.
The following registry entries are created to run packe.pif on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
winbar.pif
packe.pif
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
winbar.pif
packe.pif
The following registry entry is set:
HKCU\Software\Microsoft\OLE
winbar.pif
packe.pif
