No shocker there, Chinese hackers are into infiltrating everything from utility companies to defense contractors.
They have been robbing defense/aerospace, bio-tech and other companies blind for years stealing any IP they can get their hands on. They have even taken to stealing from universities as well and their researchers even have the audacity to republish stolen scientific papers word for word in their own academic journals and claiming them as original research.

You can at least respect the Russian hackers for what they are, a criminal enterprise and they are after one thing: Money! They are very good at what they do and won't go after any companies in there own country.

The Chinese on the other hand will still from anyone, anytime anywhere and then act like they created something original.
