Suspect Su Bin worked with two unnamed Chinese hackers to get the data between 2009 and 2013, and Su attempted to sell some of the information to state-owned Chinese companies, prosecutors said yesterday.
The three hackers targeted fighter jets such as the F-22 and the F-35 as well as Boeing's C-17 military cargo aircraft program, according to a criminal complaint filed in US. District Court in Los Angeles that was unsealed Thursday.
US Department of Justice spokesman Marc Raimondi said the conspirators are alleged to have accessed the computer networks of US defense contractors without authorization and stolen data related to military aircraft and weapons systems.
"We remain deeply concerned about cyber-enabled theft of sensitive information, and we have repeatedly made it clear that the United States will continue using all the tools our government possesses to strengthen cyber security and confront cybercrime," Raimondi said.

"We appreciate that the government brought its concerns about a potential compromise of our protected computer systems to our attention," the company said in a statement.
Accusations of hacking by China and counterclaims of such activity by the U.S. Government have strained US-Chinese relations. Chinese hacking has been a major theme of US-China discussions this week in Beijing, though both sides have publicly steered clear of the controversy.
