It's neither of the above. The goal is not to actually hack a system and change votes(and thus leave a trace) but to cast doubt onto the integrity of the vote as a whole. Thus cuing <tinfoil> any reason to throw out results of an election. I'm not going to speculate on the actors or their motives behind this though, and it could be many layers deep... But I promise you, that's the long play currently underway.
