Description:

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.
