This basic video series may help: http://www.watchguard.com/tips-resources/video-tutorials/botnets-part-one.asp http://www.watchguard.com/tips-resources/video-tutorials/botnets-part-two.asp http://www.watchguard.com/tips-resources/video-tutorials/botnets-part-three.asp http://www.watchguard.com/tips-resources/video-tutorials/botnet-source-code-for-overachievers.asp 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.

WatchGuard: Stronger Security, Simply Done -----Original Message----- From: full-disclosure-bounces () lists grok org uk [mailto:full-disclosure-bounces () lists grok org uk] On Behalf Of RandallM Sent: Friday, September 16, 2011 8:38 AM To: full-disclosure () lists grok org uk 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 RandyM a.k.a System _______________________________________________ Full-Disclosure - We believe in it.
