A month ago I have bought Rootkits, Subverting the Windows Kernel by Greg Hoglund and James Butler and I find it superb. If you are a rootkit developer or looking to be one, this is a must have book that you need to get a hold of. It teaches you generally the stuffs you want to learn such as hiding processes, files and directories, registries and lots more. Conquering the kernel level as well as beating up Antiviruses are one of the topics that are discussed on! Recently I am busy with my final years so I hope I can find time to post some useful articles.
