BEIJING (AP) — Cyberattacks that stole massive amounts of information from military contractors, energy companies and other key industries in the U.S. and elsewhere have been traced to the doorstep of a Chinese military unit, a U.S. security firm alleged Tuesday.
China's Foreign Ministry dismissed the report as "groundless," and the Defense Ministry denied any involvement in hacking attacks.
