How Hackers Worm Their Way Into Factories

摘要

At a September conference in Vancouver, Liam O Murchu, a researcher with the computer security firm Symantec, used a simple air pump connected to an industrial computer to pop a balloon. The computer's program called for the pump to stop before the balloon burst. But O Murchu had loaded the Stuxnet worm onto the machine, which let him order the pump to keep going. That, he says, shows what can happen when bad guys gain control of industrial systems: "Imagination is the limit."rnThe spread of the Stuxnet computer worm has heightened fears about the security of industrial control computer systems that run factories and power plants.
