I don't believe that the kid knows how to hack at all! Its likely a prank being pulled by somebody else that's trying to make Eric look like an actual threat. The guy said he'd been trojaned earlier with keyloggers. No way does that 14 year old kid have an idea of how to do that, especially one this annoying.
Besides have you seen his last video? Complete turnaround from the attacks he's made before but he's now on the defensive and with a completely different tone/tact. He was reading a script about some kind of legal action against LIAT and another guy (which i'd say he'd be hard pressed to have a basis for considering his threats of hacking and making LIAT his "target")
