It was January 2010, and investigators with the International Atomic Energy Company had just completed an inspection at the uranium enrichment plant outdoors Natanz in central Iran, once they realized that something was off throughout the cascade rooms the place 1000's of centrifuges have been enriching uranium.
Natanz technicians in white lab coats, gloves and blue booties had been scurrying out and in of the "clear" cascade rooms, hauling out unwieldy centrifuges one after the other, each sheathed in shiny silver cylindrical casings.
Any time workers on the plant decommissioned broken or otherwise unusable centrifuges, they had been required to line them up for IAEA inspection to confirm that no radioactive materials was being smuggled out within the gadgets earlier than they were removed. The technicians had been doing so now for more than a month.
Normally Iran replaced up to 10 percent of its centrifuges a yr, due to material defects and different issues. With about eight,seven-hundred centrifuges put in at Natanz at the time, it might have been normal to decommission about 800 over the course of the year.
But when the IAEA later reviewed footage from surveillance cameras installed outside the cascade rooms to monitor Iran's enrichment program, they have been shocked as they counted the numbers. The employees had been changing the models at an incredible price - later estimates would point out between 1,000 and 2,000 centrifuges were swapped out over a couple of months.
The question was, why?
Iran wasn't required to reveal the explanation for replacing the centrifuges and, officially, the inspectors had no proper to ask. Their mandate was to watch what occurred to nuclear material at the plant, not preserve track of apparatus failures. However it was clear that something had broken the centrifuges.
What the inspectors didn't know was that the reply they were searching for was hidden throughout them, buried within the disk area and reminiscence of Natanz's computers. Months earlier, in June 2009, someone had silently unleashed a classy and destructive digital worm that had been slithering its means by way of computers in Iran with only one intention - to sabotage the nation's uranium enrichment program and prevent President Mahmoud Ahmadinejad from constructing a nuclear weapon.
However it might be nearly a yr before the inspectors would study of this. The reply would come only after dozens of computer safety researchers all over the world would spend months deconstructing what would come to be often known as essentially the most complicated malware ever written - a bit of software that may finally make history as the world's first actual cyberweapon.
