How did Stuxnet get to its target if the computers were air-gapped?
Stuxnet used USB-delivered malware to get its payload into the air-gapped centrifuges. This technique appears to be a common trick in the CIA repertoire for striking air-gap systems. Project Sauron, another advanced piece of malware, hides on a USB drive to get into air-gapped targets.
