The Obama Administration intends to announce on Thursday that North Korea is responsible for the hacking of Sony Pictures, just a week after the FBI conceded they had no evidence at all of North Korean involvement. What changed?
Not much, from the looks of it. There is little evidence gathered to point to anyone at this point, certainly none that has been publicly released, and what is out is purely circumstantial.
Evidence is being replaced in this case with official certainty, which seems to be a function of growing eagerness to pin the hacking on somebody, and of North Korea being the most high-profile suspect.
Reports out of Sony recently were that whoever the hackers were, they almost certainly had insider help. That doesn’t necessarily prove who did it, but efforts to label North Korea as guilty are likely to derail any further inquiry into the matter.
