The United States and Israel would have to rely on engineers, maintenance workers and others — both spies and unwitting accomplices — with physical access to the plant. “That was our holy grail,” one of the architects of the plan said. “It turns out there is always an idiot around who doesn’t think much about the thumb drive in their hand.” >In fact, thumb drives turned out to be critical in spreading the first variants of the computer worm; later, more sophisticated methods were developed to deliver the malicious code. >The first attacks were small, and when the centrifuges began spinning out of control in 2008, the Iranians were mystified about the cause, according to intercepts that the United States later picked up. “The thinking was that the Iranians would blame bad parts, or bad engineering, or just incompetence,” one of the architects of the early attack said.
