Four members of an alleged computer hacking ring were charged with stealing more than $100 million worth of software and data – used to train military pilots and related to Microsoft Corp’s (MSFT.O) Xbox gaming console – the U.S. Justice Department said Tuesday. Prosecutors said the ring hacked into the computer networks of Microsoft and some of its partners between January 2011 and March 2014 to steal source code, technical specifications and other information for the Xbox One gaming console, which had not been released at the time of the attacks.
