Using cyber tools, one of our adversaries, maybe Iran, maybe North Korea, or possibly, a criminal enterprise, takes over the operations of a drinking water utility. Two days later, in another part of the U.S., the same happens at three drinking water utilities. But when it happens again two days later at five additional drinking water utilities, including in a midsize city, it becomes national news. There is a run on bottled water in supermarkets, gas stations, corner stores. The president addresses the nation, assuring everyone that there is no reason to worry, that nearly all water is safe to drink.
