Stuxnet is a computer worm discovered in 2010, designed to target industrial control systems, particularly those used in nuclear facilities. It specifically aimed at Iran's Natanz facility, where it disrupted the operation of centrifuges used for enriching uranium. Stuxnet is notable for its sophisticated design and ability to cause physical damage while remaining hidden from operators. The worm spread through removable drives and exploited multiple vulnerabilities in Windows systems. It is widely believed to be a joint project of U.S. and Israeli intelligence agencies, marking a significant development in cyber warfare. Stuxnet demonstrated how digital attacks could have real-world consequences.
