Now, thanks to documents released by Edward Snowden, the true scale of the NSA’s scope and power is coming to light. Besides spending billions of dollars to ingest and analyze the worlds’ electronic communications, the NSA has set out to dominate a new battlefield – cyberspace. We examine the science and technology behind cyberwarfare and ask “Are we are in the midst of a new arms race?” Sophisticated stealth programs such as the Stuxnet worm can take over and destroy the control systems regulating everything from food factories to gas pipelines, power plants and more – even our cars. While the destruction of Iranian centrifuges may have delayed Iran’s bomb program and forestalled an Israeli strike, the Stuxnet attack has opened a Pandora’s Box and now America’s own infrastructure is vulnerable. With leading defense experts and investigative journalists, we examine the chilling new reality of cyberwar in which no nation or individual is safe from attack.
