From my personal experience, they seed foreign factories with Military Hackers. It happen to us back in 2004 and we ended up closing the factory since it became a huge headache. They were constantly trying to get into our financials, HR and R&D network. It was comical when we would send a team to confront the employee. They would basically stand up and walk out without saying a word. There was nothing we could do. I still don't know how a company thinks it can remain secure having operations in China.

Samsung announced today that the Chinese stole their new bendable screen technology.
