U.S. intelligence agencies have pinpointed many of the Chinese groups responsible for cyberspying in the U.S., and most are sponsored by the Chinese military, according to people who have been briefed on a U.S. intelligence investigation.Armed with this information, the U.S. has begun to lay the groundwork to confront China more directly about its expansive cyberspying campaign.
