large scale Cyberattack on America is very likely according to Investigative journalist Ted Koppel. A crippling first strike can be fought with laptops instead of large armies. The Electrical Grid requires constant internet communication to carefully balance generation vs. demand. The same Programmable Logic Controllers that were infected with the Stuxnet virus damaging Iran centrifuges are used to control electric generators and power distribution. But you probably didn’t hear about ~1000 power plants in US and Europe that got infected with a Russian virus in 2014. “Dragonfly” just seemed to be just waiting for a command to execute something. Grid security is as strong as the lower common denominator. Deregulation has allowed many small companies to provide power who can’t afford cyber security the big companies used to provide.

Cyberattack Examples:

  • US outages happen every 4 days due to Cyberattacks and a small number of physical attacks
  • Russian SW bug “Dragonfly” infected 1000 power plants in US & Europe July 2014
  • Ted Koppel’s 2015 book “Lights Out” says attack is likely
  • Russia’s “BlackEnergy” Malware brings down Ukraine Dec 2015 and leaves ~300K people w/o power
  • Israel paralyzed by largest ever cyberattack likely by Iran Jan 2016
