More Information
W32/Rbot-BAL is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-BAL spreads to other network computers by exploiting common buffer overflow vulnerabilites, including: WKS (MS03-049) (CAN-2003-0812) and ASN.1
(MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Rbot-BAL 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.
