Cyber warfare used to be the stuff of sci-fi movies and military exercises. But with the advent of the Stuxnet worm, the Sony Pictures hacking—which was allegedly carried out with the backing of the North Korean government—and this week’s assault on German government websites, large-scale cyber attacks with suspected ties to nation states are growing increasingly prevalent.
Few people have lifted the veil on cyber warfare like Edward Snowden, a former NSA contractor who leaked a massive number of documents to the press.
Last June, journalist James Bamford, who is working with NOVA on a new film about cyber warfare that will air in 2015, sat down with Snowden in a Moscow hotel room for a lengthy interview. In it, Snowden sheds light on the surprising frequency with which cyber attacks occur, their potential for destruction, and what, exactly, he believes is at stake as governments and rogue elements rush to exploit weaknesses found on the internet, one of the most complex systems ever built by humans. The following is an unedited transcript of their conversation.
