L-3 Communications Holdings, Inc. Data Breach (2013)

Measured in millimeters, the tiny device was designed to allow drones, missiles and rockets to hit targets without satellite guidance. An advanced version was being developed secretly for the U.S. military by a small company and L-3 Communications, a major defense contractor. On Monday, Sixing Liu, a Chinese citizen who worked at L-3’s space and navigation division, was sentenced in federal court here to five years and 10 months for taking thousands of files about the device, called a disk resonator gyroscope, and other defense systems to China in violation of a U.S. arms embargo.
