More Information
W32/Rbot-AUY is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-AUY spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), PNP (MS05-039) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Rbot-AUY 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-AUY copies itself to <System>\msnfilen.exe.
The following registry entries are created to run msnfilen.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Service Monitor
msnfilen.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Service Monitor
msnfilen.exe
The following registry entry is set:
HKCU\Software\Microsoft\OLE
Service Monitor
msnfilen.exe
