That's what he was charged with, but I'd argue that he went to jail for being a dumbass.  His 'white hat' defense was *somewhat* undermined by the fact that he sent the data dump to Gawker *before* informing ATT of the breach and also that whole thing where, the *the night before his sentencing,* he did a Reddit AMA where he threatened to hack ATT again.

I in no way want to suggest that he isn't an idiot lol, or that he was completely in the right.  tbf though, it was a time when companies ignored security unless the media put a spotlight on it.  But the actual 'crime' was a joke.
