Stuxnet was a joint NSA-Mossad cyberweapon that destroyed approximately 1,000 Iranian nuclear centrifuges at the Natanz enrichment facility while displaying normal readings to operators. A Dutch mole working for the CIA and Mossad physically planted the malware. The operation, codenamed 'Olympic Games,' set Iran's nuclear program back by an estimated two years and established the precedent for nation-state cyber warfare.
