Cybergeddon (from tech. cyber-, lit. "computer"; Hebrew: Megiddo, extracted from Har Megiddo ("mountain of final battle") refers to cataclysm resulting from a large-scale sabotage of all computerized networks, systems and activities. It combines cyberterrorism, cyberwarfare, cybercrime, and hacktivism into scenarios of wide-scale internet disruption or economic collapse. Economic or industrial infrastructure could be targeted, such as banks or industrial control systems. Since 2012, the amount of Internet-based attacks and their complexity have increased.
"Cybergeddon is a possibility," FireEye CEO Ashar Aziz explained in an interview with Bloomberg: "Attacks on critical infrastructures such as the power grid or financial institutions could wreak havoc not just on United States economy, but in fact, the world economy."
