Precisely ascribing the origins of a malware attack, with 100% confidence, to one specific nation state is a very hard problem to solve. The time/effort that it would take for one nation to launch an attack on a 2nd party, seeming to come from a third-party, or one of their own adversaries, is not very great.

At least not with the 100% confidence that politicians would want before the US military starts dropping JDAMs on buildings.

I would give fairly even odds that something like this is the work of an organization nation state, and also even odds that it's the work of some underemployed teenagers in a basement.
