The others are similar.
You should have a look at the spreading mechanism for the code. I haven't
really thought about the effects of the way it perturbs the address ranges
it attacks, but I think if there is someone with a whole slew of
infected machines with a different-third-bit-of-dotted-quad as your
network then you can expect a lot of hits.

Technically, yes. Legally, almost certainly not :-)
There is an easier way that smurfing. Remember that this virus installs a
trojan _and_ drops cmd.exe into a scripts directory :-)
telnet victim.com 80
GET /root.exe HTTP/1.0
One less machine for someone to disinfect, one more machine for someone to
reinstall. (not really; IIS should not have full privs.).
There are working examples out there, apparently.

It's not chewing up an appreciably piece of my bandwidth :-)

I'm just very glad there isn't a version out there which attacks
NT-4.0; AFAIK this is a W2k + IIS bug only. Apparently all that's really
needed is to change the offset to get things to work for NT-4.....
