Book excerpt: You Can't See It, but it's there, hidden in your home PC. A threat so potent it could destroy massive amounts of data and shut down power plants, fuel supplies, space satellites, the armed forces, millions of computers, and even parts of the Internet. A virtually undetectable but devastating new weapon is cyberwarfare, the next wave of terrorism, and it could be launched from your very own computer. Thousands of computer super-viruses, monster worms, and zombies created by terrorists and rogue governments are the new tools of war with the potential for catastrophic results. In this chilling account, military expert and on-air analyst James F. Dunnigan sounds the alarm on what could be the nation's next surprise attack -- a cyber Pearl Harbor just waiting to happen. Every day, there are warnings of computer viruses and Internet weaknesses with the potential to disrupt society. Most are the work of amateur hackers. But consider also the super zombies, military-grade computer weapons being created by government cyberwar units. Virtually undetectable, they have the power to destroy everything, lethally spread via the Internet, and hide on home computers, waiting to be unleashed. Despite constant warnings about our cyber vulnerability and billions of dollars spent defending our networks, the risk of catastrophic cyber attacks continues to grow. Now, Dunnigan explains the rules of cyberwar -- what it is, what could happen, and how to protect yourself from becoming a pawn. From real-life attack scenarios to explanations of monster viruses, from cyberwarriors to what forces pose the most dangerous threats, Dunnigan offers clear, concise information for fighting back against a phantom enemy that may be the deadliest we've ever known.
