OK, his client was a reality star. But now he's working for a controversial president. Who's under investigation by various agencies, probably including rogue elements of the NSA.

If there aren't security firms that handle stuff like that, isn't that quite the market opportunity? From what I know, one would start with an iPhone. And then tweak for known fails. Buy the various hacking services/systems, and test against them. Not cheap, I know. And not easily doable without connections. But hey, better safe than sorry.
