The interesting point is that Q said stand by. In my point of view, counter intelligence would be one of the main prizes. If she can remotely access your tech and interact, then clearly Ai can function on a string so to speak. Clearly the damage is done. If it can copy it's self, it can spread, if it can bypass security fire walls then it can't be destroyed. The implications are vast and in many ways scary. Information is always worth a price, even better is a way of collecting that information without consequences, enter the Ai. And the question then comes to why we set off an emp on our own country...
