Cyberwarfare is a new form of war in the era of technology that is used by governments like the United States, China, and Russia to compromise security and hack infrustructure. The US government engages in cyber attack and is also focused on developing tech to defend against them through cybersecurity to prevent things like data breaches. The two earliest major cases of cyber warfare were Stuxnet worm and Not Petya ransomware. Artificial intelligence is also used to improve cyberattacks in cyber war since AI can automate the processes of identifying and executing on exploits in code.
