More Information
W32/Rbot-BAE is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-BAE 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) and ASN.1
(MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Rbot-BAE 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-BAE copies itself to <System>\mswinscks.exe.
The following registry entries are created to run mswinscks.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Microsoft Winsock
