China hacked into Pentagon computer network

China's military successfully hacked into the Pentagon's computer network, it was reported reported Tuesday, although the Chinese government dismissed the accusation as groundless.

While the Pentagon declined to say who was behind the hacking, which led to the shutdown of a computer system serving the office of Defence Secretary Robert Gates, officials told the paper it was China's People's Liberation Army.

"Against the background of good momentum towards the improvement of Sino-US military ties, some people are making groundless accusations that the Chinese military is attacking the networks of the US defence department," Jiang told journalists when asked about the Financial Times report.
