More Information
W32/Rbot-AJQ is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-AJQ 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.
W32/Rbot-AJQ spreads:
- to other network computers infected with: Troj/Kuang, Troj/Sub7, Troj/NetDevil, W32/MyDoom, W32/Bagle and Troj/Optix
- to other network computers by exploiting common buffer overflow vulnerabilites, including: RPC-DCOM (MS04-012), WebDav (MS03-007), MSSQL (MS02-039) (CAN-2002-0649) and Dameware (CAN-2003-1030)
- by copying itself to network shares protected by weak passwords
The following patches for the operating system vulnerabilities exploited by W32/Rbot-AJQ can be obtained from the Microsoft website:
