The infosec community ID'd the main suspect as Shahana Manjra, a network administrator in the payroll department where they had just learned that Mitt Romney's company Bain was firing all of their women right after Sony had hired a male executive for more than twice the pay of a woman with the same title. Manjra got in touch with some feminist hackers online and soon Sony was hacked by the "GOP". Then Crowdstrike pulled out of their ass that it was North Korea and the entire infosec community went silent and accepted it.
A CIA executive had a talk with a Sony executive around the same time.
