I haven't done much in this area, but http://www.amazon.com/Rootkits-Subverting-Windows-Greg-Hoglund/dp/0321294319/ref=sr_1_2?ie=UTF8&qid=1329145052&sr=8-2 was a decent introductory read. It's from 2005 and is probably dated now, but Syngress has a couple of others that seem like they would be of interest to you: http://www.amazon.com/Managed-Code-Rootkits-Hooking-Environments/dp/1597495743/ref=sr_1_3?ie=UTF8&qid=1329145052&sr=8-3

rootkit.com used to be a good resource as well, but it's not loading at the moment for me. I'm not sure if that's still around or not.

Yea, that's correct. He's also the co-author of the first book I recommended.

I never participated there, so aside from hearing about that ordeal, I really don't know if it was ever brought back up. It very well may not have been.
