By Chris WysopalIn the days following 9/11 we heard alarmist warnings of a coming wave of cyberterrorism. In the early days of the war in Afghanistan when an Al Qaeda computer was found, it was treated as evidence that terrorists knew how to use computers so therefore they would soon be sending worms to shut down or blow up our power plants. During that time I was interviewed on a CNN talk show describing what a terrorist might be doing with a computer that was found to have computer aided design (CAD) software on it. I said it might be used to figure out the best place to plant a bomb to cause the most damage to a structure. This wasn’t cyberterrorism. It was using the computer as an engineering tool. Somehow this got lost by the host of the show who kept on plugging away that cyberterror from Al Qaeda was coming soon. That never materialized and in the last 10 years I don’t think there has been any documented cases of cyberterrorism.
