At last some sane analysis that doesn't involve "terorists" or similar bullshit. Though I find 5 ("The attackers only latched onto “The Interview” after the media did – the film was never mentioned by GOP right at the start of their campaign. It was only after a few people started speculating in the media that this and the communication from DPRK “might be linked” that suddenly it became linked. ") contradicting to 2 ("<...> the code was written on a PC with Korean locale & language"). Anyway, I would bet my money on the insider too -- the low sophistication level of malware combined with excessive knowledge of internal infrastructure speaks for itself.
