I did not say that at all.
I’m putting my money on an insider (current or past) who’s pissed off at SONY. If not, the had to have help from the inside, but in fairness:
I should say that if some SONY system admin left their credentials lying around somewhere, then it could have been someone who’s NOT on the inside. Still, they would have needed a road map.
Then why did the FBI issue a press release documenting the reasons that the hack points to North Korea?
