One person on Bugtraq posted a script that would firewall a machine that was
issuing these probes, but others pointed out that this could be use to deny
proxy users access to your site by issuing fake probes thus getting the proxy

It would be nice if you could launch a retaliatory attack back that would
disable the attacker, but I believe this has some legal issues. With the new
anti-terrorism laws, I don't know if I would want to even try this for academic
purposes (Free speech? What free speech? There's that "chilling" effect again.)

Bottom line is that code red is annoying, but totally harmless to you (other than
eating up your bandwidth...)

Honestly, I don't understand why ISP's are not taking a more proactive approach
here.  With flat rate bandwidth (most customers), they lose money due to code
red type worms. Most of the code red attacks I've seen are from home machines
on cable / DSL.
