More Information
W32/Rbot-AVO 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), WINS (MS04-045), MSSQL (MS02-039) (CAN-2002-0649) and PNP (MS05-039) and by copying itself to network shares protected by weak passwords.
W32/Rbot-AVO 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-AVO copies itself to <System>\dma.exe.
