More Information
W32/Rbot-ASZ is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ASZ may spread to remote network shares with weak passwords or by exploiting any of the following system vulnerabilities: RPC-DCOM (MS04-012), PNP (MS05-039), ASN.1 (MS04-007).
W32/Rbot-ASZ 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.
