Late last Wednesday, the Department of Justice announced that Su Bin, a Chinese national living in Canada, had plead guilty to "participating in a years-long conspiracy to hack into the computer networks of major U.S. defense contractors, steal sensitive military and export-controlled data and send the stolen data to China." Over several years, under Su's direction, two hackers stole some 630,000 files from Boeing related to the C-17 military transport aircraft as well as data from the F-35 and F-22 fighter jets. The information included detailed drawings; measurements of the wings, fuselage, and other parts; outlines of the pipeline and electric wiring systems; and flight test data.

Su's conspirators remain unidentified and at large. The 2014 indictment refers to the co-conspirators as "affiliated with multiple organizations and entities." The plea announcement refers to them as "two persons in China" and says nothing more about them. But in documents submitted as part of Su's extradition hearing, the U.S. government identified them as People's Liberation Army (PLA) hackers. The documents included intercepted emails with digital images attached that showed military IDs with name, rank, military unit, and date of birth.
