More Information

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

W32/Rbot-BAV 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), Veritas (CAN-2004-1172), MSSQL (MS02-039) (CAN-2002-0649) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.

W32/Rbot-BAV 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-BAV copies itself to <System>\mcafe.exe.

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

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
mcafe Software
mcafe.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
mcafe Software
mcafe.exe

The following registry entry is set:

HKCU\Software\Microsoft\OLE
mcafe Software
mcafe.exe
