I work for a large financial firm. I'm sure we have some government contracts somewhere in the company, we're huge. But we're definitely not national defense, the large majority of our businesses are consumer-facing.
And we interviewed one of these.
A few little things made us think the application was weird. Then during the interview, they claimed to be from a smallish place in New Jersey. One of our people grew up close to there and asked some questions about local things. They had no idea and covered poorly. Then my coworker just blurted out, "you're North Korean, aren't you?"
Dude immediately bailed on the call.
I assume the goals were money, data access and maybe access to the network. In any case, they aren't just going after defense actors.
