IMHO "fixing" whitehouse.gov scales much better than "fixing" *.mil in a
number of interesting ways.
YMMV

Actually, what they did was disgustingly simple - it was observed that (1)
the IP address, not the hostname, of www1.whitehouse.gov was hardcoded
into the worm, and (2) the worm made a connection to port 80 on that IP
address to make sure the host was live before launching the DoS.
Given these two weaknesses, all that the whitehouse.gov admins had to do
was move the server to a different IP, and nullroute the old IP. The worm
tried to contact the old IP, couldn't open a socket, and quietly went
dormant.
I would expect that the next worm of this type will have neither of these
vulnerabilities.
