I'm dubious that North Korea did this particular attack.

That said, acting as if North Korea can't pull off this sort of attack is dangerously complacent.

The thing is no one should care. It isn't unique NK capability. Hacking is the domain of non-state actors, and knows no real political boundaries - at least on this level.

We're not talking about stuxnet, where it's likely wetwork teams planted it in the targets. We're talking about a run of the mill corporation with bad security getting owned - it was going to happen because the bar to clear for doing it just wasn't very high.
