Stuxnet is a computer worm discovered in 2010, spreading via corrupted USB drives and was predominantly used in cyber warfare. The malware targeted industrial control systems used to control nuclear power plants and other industrial facilities.
Stuxnet was so powerful that it was able to control Iran’s nuclear centrifuges and cause physical damage. While the financial damage caused by Stuxnet was not as large as other malware, it showed how sophisticated malware is capable of physically disrupting critical infrastructure.
