What I don't understand is why the hacker (whose full name is used in the article - alias?) is being public about this? Shit security or not, they made a clear cut black hat move purely for money. Or I suppose the other factor is fame/infamy. Pretty sure there are at least a few pissed off hackers among those 50M people who would want to track this person down digitally and pull something as retaliation.
I'm going out on a limb, but based on signal from the article and actions the person has taken, I don't think they're mentally well.
His other bombastic comments to press and relatives also make him sound insecure and immature. Obviously he had to be somewhat adept and dedicated to gain access, but he didn't discover any incredible exploit here. He also takes credit for discovering a well known zero-day but admits he had nothing to do with the code for the exploit. To me that supports the idea that he hangs out in black hat circles because he wants to be one of the 'cool kids', put in the time and got lucky. I imagine the press love that because a lot of the public doesn't really know the difference.
