The indictment, which includes charges of trade-secret theft and economic espionage, was issued in Pittsburgh, where most of the companies are based.The charges dramatize a longtime Obama administration goal to prosecute state-sponsored cyber threats, which U.S. officials say they have grappled with for years. A recent government report said that more than 40 Pentagon weapons programs and nearly 30 other defense technologies have been compromised by cyber intrusions from China. The cybersecurity firm Mandiant also has linked a secret Chinese military unit to years of cyberattacks against U.S. companies.last_img
