Try googling the question in When Code Red was in
its first week of terror, several people posted scripts that 1) halted the
offending machines or 2) emailed the "admins". I'm sure you can find a
perl script for #2.

Or spend a few minutes with awk and whois in a bash script.


PS - My figures are pretty similar to yours. In the last three months, my
personal server has had 354,000 scripties hit it in one form of attack or
another. I snort and move on....
