NK may be a sideshow as far as a lot of interested parties are concerned. The benefit (if you can call it that) is that the presently-tapering security contractor gravy train gets a new shot in the arm, the Feds have a chance to set up "partnership" agreements with any number of tech firms that they just alienated during the NSA fiasco, and a much higher level of generalized network surveillance becomes a thing that plenty of companies start thinking they want.

I obviously don't know the story behind this. The point is, there are plenty of opportunistic and self-serving domestic interests who probably don't either but can nevertheless turn this hack into a very beneficial event, regardless of who did it. From their perspective, NK being the source is actually the best-case scenario.
