Summary
W32.Dabber propagates by exploiting a vulnerability in the FTP server component of W32.Sasser.Worm and its variants. It installs a backdoor on infected hosts and tries to listen on port 9898. If the attempt fails, W32Dabber.A tries to listen on ports 9899 through 9999 in sequence until it finds an open port.
Solution
Solution
- Disable access to port 445 and Dabber remote shell by using a firewall - Apply Microsoft MS04-011 patch - Update your virus definitions
