New York Times – U.S. Blames China’s Military Directly for Cyberattacks:
The Obama administration on Monday explicitly accused China’s military of mounting attacks on American government computer systems and defense contractors, saying one motive could be to map “military capabilities that could be exploited during a crisis.”
From the report itself:
In 2012, numerous computer systems around the world, including those owned by the U.S. government, continued to be targeted for intrusions, some of which appear to be attributable directly to the Chinese government and military. These intrusions were focused on exfiltrating information. China is using its computer network exploitation (CNE) capability to support intelligence collection against the U.S. diplomatic, economic, and defense industrial base sectors that support U.S. national defense programs.
