Where would this AI live? Presumably it would use a botnet as it's substrate, I cannot think any other place to slip into. What would it do? Presumably it would survive only if it did not crash or totally corrupt the existing machines so their owners would manage to use their computers just as before. Like other bot networks. Presumably to maintain any sort of integrity and to leverage non trivial computational resources the bots would need to communicate. I don't know how discoverable botnets are in general before a massive DOS event or such but I presume the discoverability of this rogue AI was on the same level as a first approximation... Fun fact: The AI in Dan Simmon's Hyperion live in a substrate that parasitically timeshares unperceptively the brains of people :)
