“Hypponen said hackers are moving from Europe to Syria, where officials worry they could launch attacks that shut down computer networks or damage critical infrastructure. He said the threat is so serious, a U.S. drone strike this summer targeted a British hacker who, U.S. and European officials said, had become a top cyber expert for the Islamic State in Syria. Authorities believe the hacker led the CyberCaliphate, a hacking group which in January attacked a Twitter account belonging to the Pentagon.
Asked to describe a ‘horror story,’ Hyppönen didn’t hesitate. He said the threat is that these groups will perpetrate an attack that cyber criminals wouldn’t even consider — because there’s no money in it. They might, for example, target the Siemens systems that control 50 percent of the world’s factory equipment.”
