This is called attention seeking behavior. I bet this guy couldn't hack his way out of a wet paper bag using a razor sharp machete.

For the record I've worked in computers sense the early 90s. 90%+ of hacks happen because the person stumbles into a vulnerability in a system and exploits it. All that BS you see on TV is exactly that its BS. RARELY does someone target a specific company and succeed at hacking them. Thus this guy is either the luckiest SOB on the whole planet or he's a lying POS taking credit for what other people have done.

As a side note wtf is with the moving the shoulders thing. That was just F-ing weird.
