This basic video series may help:

That said, we made that ages ago. It is quite dated. Most modern botnets have started to use HTTP C&C channels, often 
encrypted. They also sometimes obfuscate their C&C via proxies and p2p. Leaked source code for Zues and spyeye probably 
would provide a better idea of how modern botnets work.

Subject: [Full-disclosure] understanding the botnet C&C..

hi
an area that I am basically "stupid" on is botnets. Not what they are
but "how" they work through IRC as the control center. Not just that
but the various modern programs used. I am aware for instance LOIC can
be used to connect to an IRC channel.. but, how then does the "herder"
do the job from IRC..how does he issue commands that all the computers
connected act upon, etc. ? My curiosity has just got the best of me
and I would like some pointers to good material that can feed it.

Sorry for the "troll" like post but I really would like to understand
this further. Have done a number of Google searching but have hope
someone here has done personal research.

been great, thanks
