More Information
W32/Rbot-AQY is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-AQY spreads:
- to other network computers infected with: W32/MyDoom and W32/Bagle
- to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012) and WebDav (MS03-007)
- by copying itself to network shares protected by weak passwords
W32/Rbot-AQY 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-AQY copies itself to <System>\MrNo4236.exe.
The following registry entries are created to run MrNo4236.exe on startup:
