An airliner's controls abruptly fail mid-flight over the Atlantic. An oil tanker runs aground in Japan when its navigational system suddenly stops dead. Hospitals everywhere have to abandon their computer databases when patients die after being administered incorrect dosages of their medicine. In the USA, a nuclear power plant nearly becomes the next Chernobyl when its cooling systems malfunction.

At first, these random computer failures seem like unrelated events. But Jeff Aiken, a former government analyst who quit in disgust after witnessing the gross errors that led up to 9/11, thinks otherwise. Jeff fears a more serious attack targeting the United States computer infrastructure is already under way. And as other menacing computer malfunctions pop up around the world, some with deadly results, he realizes that there isn't much time if he hopes to prevent an international catastrophe. Written by a global authority on cyber-security, Zero Day presents a chilling 'what if' scenario that, in a world completely reliant on technology, is more than possible today... it's a cataclysmic disaster just waiting to happen.'Mark came to Microsoft in 2006 to help advance the state of the art of Windows, now in his latest compelling creation he is raising awareness of the all too real threat of cyber-terrorism.' Bill Gates'CyberTerrorism. Get used to that word and understand it because you're going to see more of it in the newspapers and hear it on the news in the not too distant future.

Schmidt, White House Cyber Security Coordinator'An up-to-the-moment ticking-clock thriller, Zero Day imagines the next 9/11 in a frightening but all too believable way. An expert in the field, Mark Russinovich writes about cyberterrorism with a mix of technical authority and dramatic verve. I was riveted.' William Landay, author of The Strangler'When someone with Mark Russinovich's technical chops writes a tale about tech gone awry, leaders in the public and private sector should take notes.'
