There are a number of IRC controlled bots that will allow
scanning of subnets for Sub7. So you will see occasional
flameups of Sub7 scans as they happen to focus on your
network. Try to connect to some of the cable modem in 24/8
and you will see more of that.
I should still have a little perl honeypot around that you can use
to find out what they try to install on sub7 infected machines.
