Also called "cyberterrorism" and "cyberwarfare," information warfare refers to cyberattacks that create havoc on a large scale. Some examples are disrupting the computers that manage stock exchanges, power grids, air traffic control, telecommunications and defense systems. Viruses, Trojans and denial-of-service attacks are part of the information warfare arsenal, and they get more sophisticated every year.
The first book to deal with the subject was "Information Warfare: Chaos on the Electronic Superhighway," by Winn Schwartau, written in 1994 just as the Internet was being commercialized. Published in 2012, "Cyber War: The Next Threat to National Security" by Richard A. Clarke and Robert K. Knake is an eye-opening book on the subject.
Before a Shooting War
Information warfare is increasingly considered as the first offensive before the start of a physical attack. The military in many countries have full-time cyberwarriors on the payroll, because the more successful a cyberattack on an early warning defense system is, the greater the success of the real attack. According to "Cyber War," North Korea may have as many as a thousand hackers stationed in China, working on knocking out systems in South Korea and other countries. See virus
