  Looks like they might have realised they screwed up.
lynx -head dhs.gov shows:

HTTP/1.0 302 Moved
Temporarily                                                  Server:

  And the netcraft site shows it switched from being win2k to Linux
today. Probably the worm got the win2k box.

  As for the worm: I noticed the net got slow. I added the LOG module
to iptables, and am not getting packets to 1434, but I did notice
interesting things of the form below. Looks like the reports about
M$ clients cheating on TCP may be valid.
