researchers found a handful of malicious files on one of the systems and discovered the world’s first digital weapon.
Stuxnet, as it came to be known, was unlike any other virus or worm that came before. Rather than simply hijacking targeted computers or stealing information from them, it escaped the digital realm to wreak physical destruction on equipment the computers controlled.
The Stuxnet computer worm that destroyed centrifuges inside Iran's Natanz uranium enrichment site was only one element of a much larger US-prepared cyberattack plan that targeted Iran's air defenses, communications systems, and key parts of its power grid
Stuxnet is a malicious computer worm, first identified in 2010, that targets industrial computer systems and was responsible for causing substantial damage to Iran's nuclear program. The software was designed to erase itself in 2012 thus limiting the scope of its effects. The worm is believed by many experts to be a jointly built American-Israeli cyberweapon, although no organization or state has officially admitted responsibility. Anonymous American officials speaking to The Washington Post claimed the worm was developed during the Bush administration to sabotage Iran's nuclear program with what would seem like a long series of unfortunate accidents.
