WASHINGTON — Computer hackers have begun targeting power plants and other critical operations around the world in bold new efforts to seize control of them, setting off a scramble to shore up aging, vulnerable systems.
Cyber criminals have long tried, at times successfully, to break into vital networks and power systems. But last month, experts for the first time discovered a malicious computer code — called a worm — specifically created to take over systems that control the inner workings of industrial plants.
In response to the growing threat, the Department of Homeland Security has begun building specialized teams that can respond quickly to cyber emergencies at industrial facilities across the country.
