This 20 minute Ted Talk discusses how a hidden cyberwar is being perpetrated for the past 2 decades online not with bullets and bombs but rather with bits and bytes. This video outlines how the US government used a custom virus, called Stuxnet, to stop nuclear weapons development in Iran and the consequence of the release of that virus code to other government entities around the world. Then the video turns its focus on these silent wars being perpetrated all over the world by nation states intent on stealing weapons technology and intellectual property from research facilities and institutions and businesses alike. Campaigns by China (suspected but not proven) and identified by intelligence agents as operation Aurora which broke into 20 top companies in the us, including Intel, Google and IBM.
