Bottrackers
I was recently creating a lightweight program to track botnet update commands. Currently it can connect to an IRC server, join a channel there and monitor the update commands. Every time it sees a certain update command it gives me a nice popup on the URL.
Originally, the program was 4096 bytes long, and I got interested on how small I can make it.
Currently the size is 2048 bytes, and if I have more time I’ll try to shave a few bytes off of it ;)
Quite a small for an IRC bot, eh?
Update (24.2.2007, 00:10 GMT+2):
The size is now 1639 bytes :)
