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.”
While some recent estimates have more than 90 percent of cyberespionage in the United States originating in China, the accusations relayed in the Pentagon’s annual report to Congress on Chinese military capabilities were remarkable in their directness. Until now the administration avoided directly accusing both the Chinese government and the People’s Liberation Army of using cyberweapons against the United States in a deliberate, government-developed strategy to steal intellectual property and gain strategic advantage.
“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,” the nearly 100-page report said.
The report, released Monday, described China’s primary goal as stealing industrial technology, but said many intrusions also seemed aimed at obtaining insights into American policy makers’ thinking. It warned that the same information-gathering could easily be used for “building a picture of U.S. network defense networks, logistics, and related military capabilities that could be exploited during a crisis.”
