You can download much more sophisticated software than this and learn step by step basics to crack encryption in minutes but for the hot stuff you'll need to know someone.

A friend of mine hacked the personal files of the head of security for one of the largest telecom corporations in the world and then phoned him on his private personal mobile on a Friday night when he was in his local pub in London. They have a scrip they read out to say there is no threat to them or their network and point out the holes in the secutiry system. They tape the calls and spend the night laughing their heads off at the responses over a few drinks... well a lot of drinks.
