“Chinese hacking of American computer networks is old news. For years we've known about their attacks against U.S. government and corporate targets. We've seen detailed reports of how they hacked The New York Times. Google has detected them going after Gmail
accounts of dissidents. They've built sophisticated worldwide eavesdropping networks. These hacks target both military secrets and corporate intellectual property. They're perpetrated by a combination of state, state-sponsored and state-tolerated hackers. It's been going
on for years. ”- Bruce Schneier(Emphasis mine)
