More Information
W32/Rbot-BFL is an internet worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-BFL spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011) and RPC-DCOM (MS04-012) and by copying itself to network shares protected by weak passwords.
W32/Rbot-BFL 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-BFL includes functionality to:
- steal confidential information
- carry out DDoS flooder attacks
- silently download, install and run new software
The following patches for the operating system vulnerabilities exploited by W32/Rbot-BFL can be obtained from the Microsoft website:
