> It's amusing that they 'lost control' of it because a simple bit of code along the lines of "if www.google.com resolves then shutdown" would be effective at detecting whether it was on the Internet or not.

Not really. The code would need to rely on or implement additional network (or DNS) code, and then also make a network connection; making it much more easily traced.

Either way, I think the "lost control" headline here is a bit much. Stuxnet, from the analysis performed, was harmless beyond the target network.
