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, the officials said, speaking on the condition of anonymity to discuss an ongoing investigation. 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.
The officials did not identify the contractor.
The data stolen was of a highly sensitive nature despite being housed on the contractor’s unclassified network. The officials said the material, when aggregated, could be considered classified, a fact that raises concerns about the Navy’s ability to oversee contractors tasked with developing cutting-edge weapons.
The breach is part of China’s long-running effort to blunt the U.S. advantage in military technology and become the preeminent power in east Asia.
