The US Department of Justice announced late Friday that a Chinese businessman has been charged with hacking into the computer systems of Boeing, Lockheed Martin and other aerospace companies. The alleged hacker, Su Bin, is accused of helping unidentified co-conspirators to identify what to steal from the companies’ networks—including data on the F-22 and F-35 fighter aircraft and the C-17 cargo plane program. Su, also known as Stephen Su, an executive for a Chinese aerospace company with offices in Canada, was arrested by the Royal Canadian Mounted Police in British Columbia on June 28, in cooperation with the FBI.
