China's army accused of global hacking

China’s army is believed to be behind a computer-hacking group that has attacked 141 companies across the world since 2006, Bloomberg reported. The group is “likely government sponsored” and is similar “in its mission, capabilities and resources” to a unit of the People’s Liberation Army, US security firm Mandiant Corp said Tuesday. The group, which mainly targets US companies, has been traced to four large computer networks in Shanghai, two of which are in Pudong New Area district, where a secret army unit is based.
