Central unanswered question in the article on wich all the speculation rests: "If this were a cyberattack, why mess with freezers?"

And yes, remember you can explain everyting by adding enough dimensions to a game of chess. But in reality? Seems the upside is near zero while the dowside is sacrifising your access.
