Hi, I am doing some research on Chinese hacking of defense contractors. There has been a great deal of attention in the news about the various Chinese theft of IP from U.S. companies, but far less about hacking efforts directed at other states. Does anyone know, for instance, whether the indigenous components used in the Shenyang J-11 (against the PRC's agreement with Russia for the Su-27 production deal) were developed by hacking Rosoboronexport servers and stealing engine/avonics from Sukhoi engineers?

Thanks.
