Chinese government hackers have compromised the computers of a Navy contractor, stealing massive amounts of highly sensitive data related to undersea warfare — including secret plans to develop a supersonic anti-ship missile for use on U.S. submarines by 2020, according to American officials. The breaches occurred in January and February 2018, the officials said… The hackers targeted a contractor who works for the Naval Undersea Warfare Center, a military organization headquartered in Newport, R.I., that conducts research and development for submarines and underwater weaponry.
Taken were 614 gigabytes of material relating to a closely held project known as Sea Dragon, as well as signals and sensor data, submarine radio room information relating to cryptographic systems, and the Navy submarine development unit’s electronic warfare library…This fact raises concerns about the Navy’s ability to oversee contractors tasked with developing cutting-edge weapons.
For years, Chinese government hackers have siphoned information on the U.S. military, underscoring the challenge the Pentagon faces in safeguarding details of its technological advances. Over the years, the Chinese have snatched designs for the F-35 Joint Strike Fighter; the advanced Patriot PAC-3 missile system; the Army system for shooting down ballistic missiles known as Terminal High Altitude Area Defense; and the Navy’s new Littoral Combat Ship, a small surface vessel designed for near-shore operations, according to previous reports prepared for the Pentagon. In some cases, suspected Chinese breaches appear to have resulted in copycat technologies…
Investigators say the hack was carried out by the Chinese Ministry of State Security, a civilian spy agency responsible for counterintelligence, foreign intelligence and domestic political security. The hackers operated out of an MSS division in the province of Guangdong, which houses a major foreign hacking department….
In September 2015, in a bid to avert economic sanctions, Chinese President Xi Jinping pledged to President Barack Obama that China would refrain from conducting commercial cyberespionage against the United States. …Both China and the United States consider spying on military technology to fall outside the pact.
