A fellow handler, whom I call Ekim Roop, wrote a challenge based on the Tarantino "Kill Bill" movie about a month ago.  Today, he posted the winners of this challenge.

If you are interested in securing sudo, ssh, and pgp/gnupg on Linux, learning a bit more about Bill Stearns' apptrace program, or reading a Kill Bill themed challenge, read the results here.

By the way, I was surprised to see old Ekim write a challenge called "Hack Bill" that did not mention Microsoft at all.  What restraint!
