The Sony hack, 2014

A major cyberattack against the United States in 2014 was a clear example of how civilians can bear the brunt of such operations. Almost all cybersecurity experts and the FBI believe that the Sony Pictures hack that year originated in North Korea. A hostile country hit a U.S. civilian target with the intention of destabilizing a major corporation, and it succeeded. Sony’s estimated cleanup costs were more than $100 million. The conventional warfare equivalent might look like the physical destruction of a Texas oil field or an Appalachian coal mine. If such a valuable civilian resource had been intentionally destroyed by a foreign adversary, it would be considered an act of war.
