The fact that they could manipulate the tightness and display output so that it could leave the bolts loose while saying that they aren’t, seems like a bigger problem.
Maybe the ransom was designed to be ongoing. I.e. as soon as you factory reset the wrench, it gets hit again with the same message, and you’d have to find some other part of the network that was messing them up.
Well, yes. There would be a root infection point outside of the wrenches themselves. The entire network would likely need to be inspected before you’d just reflash and move along like everything was better.
