Ok, perhaps I'm just bitter. But I'm very tempted at this point to let the M$ IIS admins hear back from the "Code Red II" worms they've got infecting their system, by doing this: 

grep 'default.ida' /path/to/access_log | awk {'print $1'} | sort -n | 
+uniq | this_perl_script.pl

...say...every two minutes or so.

It would be cool if someone would expand this to do a whois query, prase the results for emails, and send $message to the admins and owners of the domains involved. 

#!/usr/bin/perl -w

use strict;
use LWP::Simple;

my $ipaddress;

# Message to the sysadmin who is infected. I've kept out unusual 
# punctuation on purpose
my $message = <<END;
You are infected with the Code Red II worm and it is bloody annoying. 
+For details head to http://www.cert.org/advisories/CA-2001-19.html
END
$message =~ s/ /_/g;

foreach $ipaddress (@ARGV) {
        my $full_url = "http:\/\/$ipaddress\/$message";
        my $junk = get($full_url);
        }
