Mum's the word for U.S. businesses hacked by China

Governments spying on each other is nothing new. Nor is corporate spying: The U.S. textile industry began after American industrial spies stole factory plans from 18th century Britain. But Dan McWhorter, managing director of cyber security firm Mandiant, says the scale of China’s state-sponsored theft of data from U.S. companies is unprecedented and difficult for a democratic society to grasp. "There’s such a firm divide between government and corporation, that it’s hard to wrap your head around," says McWhorter. "In a communist government, the government and industry are tied together and they’re hard to distinguish at times."
