Stuxnet cyberattack disrupted Iran's nuclear centrifuges in 2009 through sophisticated malware.

Summary

In 2009, Iran's nuclear program experienced systematic failures in its centrifuge operations caused by Stuxnet, a state-sponsored cyberweapon believed to be developed by the US and Israel. The malware infiltrated industrial control systems at Iran's nuclear facilities, causing centrifuges to malfunction while masking the sabotage from monitoring systems. This represents one of the first known instances of code-based cyber warfare directly impacting physical critical infrastructure.
