Christopher has some early 2000's videos on youtube He seems to be most well known for his work with DirecTV and NDS which led to legal troubles.

This February 2008 Blackhat talk seems to be the first public talk given about the methods Christopher uses to reverse engineer IC'''Links'''s.

How to Reverse-Engineer a Satellite TV Smart Card - This June 2008 Wired.com video and [https://www.wired.com/2008/05/tarnovsky/ article] is a brief look into Christophers lab and a very high level look at what he does to gain access to the silicon wafer.
