Newer/remodeled hotels and airports are full of these things now. They don't exactly jump out at you, they would be easy enough to miss.
AFAIK these things are just dumb voltage sources, they don't have any USB controllers that could be hacked. At least, the ones you and I can buy don't. But there isn't, in principle, any reason why they couldn't have such controllers, either.
