More than 250,000 U.S. Department of State cables recently released by WikiLeaks links China to the December 2009 hack of Google's computer systems, according to Computerworld.
The New York Times says:
China's Politburo directed the intrusion into Google's computer systems in that country, a Chinese contact told the American Embassy in Beijing in January, one cable reported. The Google hacking was part of a coordinated campaign of computer sabotage carried out by government operatives, private security experts and Internet outlaws recruited by the Chinese government.
Back in January, a researcher found code that linked the cyber attacks on Google and a number of other companies to China. In fact, the attacks were traced to computers at two schools in China, but China denied any involvement.
