The 2010s marked the moment cyberattacks became tools of national power. In 2010 the discovery of Stuxnet revealed a sophisticated piece of code designed to physically interfere with industrial equipment used in a nuclear program. For the first time the public saw clear evidence that software could cross from the digital world into physical sabotage, and that governments were likely behind such operations. It redefined what a cyberweapon could be.

State-linked activity grew more visible throughout the decade. The 2014 Sony Pictures hack combined data theft, destructive wiping, and public intimidation, and was widely attributed to a nation-state actor. Attacks were no longer only about money or disruption. They were about coercion, espionage, and sending political messages.

Extortion scaled in parallel. In 2017 the WannaCry outbreak spread rapidly across the globe, locking files on hospital, business, and government systems and demanding payment to restore access. It showed how a single widespread vulnerability could cause worldwide damage within hours. Criminal groups refined this model into ransomware as a service, in which skilled developers rent their tools to less technical affiliates in exchange for a share of the proceeds.

By the close of the 2010s, cybersecurity had become inseparable from geopolitics and economics. Defending networks now meant defending hospitals, utilities, elections, and critical services.
