BlackHat Challenge

SensePost announces a BlackHat 2012 training giveaway via a crypto challenge where participants analyze a provided PCAP (authentication traffic only) and leaked client/server code from a fictional internal messaging system to recover a 7-character lowercase alphanumeric shared secret and derive the encryption key (kc); the first correct submission wins a free course pass and a limited edition t-shirt, with an update noting a winner has been confirmed.
