Amazon.com just posted my five star review of Managed Code Rootkits by Erez Matula. From the review:
Managed Code Rootkits (MCR) is one of the best books I've read in 2011. MCR is a one-man tour-de-force through the world of malicious software that leverages managed code for its runtime. Prior to reading the book I was only vaguely aware of the concept and implementation. After reading MCR, I am wondering when we might see more of this technique in the wild. Author Erez Metula does almost everything right in MCR, and I strongly recommend reading it.
