Panetta warns of imminent "Cyber Pearl Harbor"
Defense Secretary Leon Panetta, speaking this week
: “An aggressor nation or extremist group could use these kinds of cyber tools to gain control of critical switches. They could derail passenger trains, or even more dangerous, derail passenger trains loaded with lethal chemicals. They could contaminate the water supply in major cities, or shut down the power grid across large parts of the country.” Later, he told reporters at the NYT to relax; this imminent threat does not mean he wants to read your email.
