The FBI and DOJ continue their effort to bring cyber hackers to justice.

Last week, Chinese national Su Bin pled guilty to stealing data related to Boeing’s C-17 military cargo plane and of trying to steal information related to U.S. F-22 and F-35 fighter jets. Bin was indicted, along with other co-conspirators, in August 2014 by a California federal grand jury of stealing computer data of The Boeing Co. and other U.S. military contractors from 2006-2014 and attempting to send the data to China.

Su will be sentenced on July 13, 2016. Although he faces up to five years in prison and a $250,000 or twice the gross gain or loss from the scheme, the gain is that China’s military planes have an uncanny resemblance to U.S. planes. How does one value that gain or loss?
