Chicago Merc. Exchange Secrets Leaked to China

chicksdaddy writes: A 10 year employee of CME Group in Chicago is alleged to have stolen trade secrets and proprietary source code used to run trading systems for the Chicago Mercantile Exchange and passed them to officials in China, where he hoped to set up a software firm to help create electronic exchanges, according to a criminal complaint filed in U.S. District Court in Illinois. Chunlai Yang, 49, is alleged to have downloaded "thousands of files" containing "source code and proprietary algorithms" used by CME to run its trading systems. The files were downloaded from a company-owned source code repository maintained by CME to Yang's work computer, then copied them to removable "thumb" drives. The complaint also cites personal e-mail correspondence between Yang and an official in China that contained proprietary CME information.
