I think the malware was a ruse. Maybe she was leaving some discrete listening devices which use quantum radio communications. Or worse, perhaps a biological pathogen. Imagine if she left a new biowar agent in Trump's vicinity, he wouldn't even need to be there, just nearby. Or maybe she was testing the perimeter, seeing how far she could get, and how the opfor operates. Lots of possibilities, and I don't buy her story at all. The Russians are active, physical opponents, the Chinese are much more devious and cunning.
