US officials told the Financial Times today that China's military hacked into the Pentagon's computer network three months ago. The reported attack would amount to to the greatest pwnage yet of DoD computers:

The Pentagon acknowledged shutting down part of a computer system serving the office of Robert Gates, defence secretary, but declined to say who it believed was behind the attack.

Current and former officials have told the Financial Times an internal investigation has revealed that the incursion came from the People’s Liberation Army.

One senior US official said the Pentagon had pinpointed the exact origins of the attack. Another person familiar with the event said there was a “very high level of confidence...trending towards total certainty” that the PLA was responsible. The defence ministry in Beijing declined to comment on Monday.
