China Government Hackers Compromised U.S Navy Contractor Computers & Stolen 614 gigabytes of Highly Sensitive Data

Chinese government hackers attacked U.S Navy contractor computers and stolen a massive amount of highly sensitive data and the Breach occurred between January and February.

The Stolen Data including the highly secret plans about the development of supersonic anti-ship missile for use on U.S. submarines which is going to implement in 2020.

Hackers have taken around 614 gigabytes of sensitive materials that are related to the U.S Navy project called Sea Dragon.

Also, it related to signals and sensor data, submarine radio room information relating to cryptographic systems, and the Navy submarine development unit’s electronic warfare library.

Attackers Specifically targeted the contractor who is work with Naval Undersea Warfare Center which is military organization headquartered.

A victimized contractor involved with conducts research and development for submarines and underwater weaponry.

According to Washington Post, 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.

In this case, U.S Navy starts the further investigation about in this breach with FBI and  a Navy spokesman, said, “There are measures in place that require companies to notify the government when a ‘cyber incident’ has occurred that has actual or potential adverse effects on their networks that contain controlled unclassified information.”

This breach effort of Chinese long time preparation and taking the opportunity to become the supreme power in military technology.

Cyberwar between U.S and China is a long time running battle and both side cyber experts are keeping attacking each other’s various government operations.

In some cases, suspected Chinese breaches appear to have resulted in copycat technologies, such as the drones China has produced that mimic U.S. unmanned aircraft.

Although the Chinese People’s Liberation Army is far better-known than the MSS when it comes to hacking, the latter’s personnel are more skilled hackers are working behind the operation and much better at hiding their tracks, said Peter Mattis, a former analyst in the CIA counterintelligence center.

In this case, Washington post agreed not to disclose the compromised missile project which was requested by U.S Navy.
