More Information
W32/Rbot-ASU is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ASU spreads by copying itself to network shares protected by weak passwords and to other network computers by exploiting common buffer overflow vulnerabilities, including: RPC-DCOM (MS04-012), PNP (MS05-039) and ASN.1 (MS04-007).
W32/Rbot-ASU 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-ASU copies itself to <System>\mswind32.pif.
The following registry entries are created to run mswind32.pif on startup:
