Dear list, We are proud to present two free XMAS 2011 hacking challenges for you! The first challenge is just "fun". Hack the file and become a music hero! The second challenge is about oracle padding. A difficult one, scratch your head and solve the challenge. A lot to learn, I promise. Interested?
