China the world's 'most sophisticated' hacker?

Per Google's Eric Schmidt in his new book

China the world's 'most sophisticated' hacker - Telegraph

And related the New York Times, Wall Street Journal, and Washington Post werealso  hacked:

Chinese Hackers Hit U.S. Media - Wall Street Journal
Wall Street Journal, New York Times Are Breached in Campaign That Stretches Back Several Years

Washington Post Joins List of News Media Hacked by the Chinese - New York Times

Why Most Companies Won't Admit They Were Hacked - Tech News Daily

What Chinese hacking means for journalism - Politico

I agree with this:

"China probably couldn’t care less that its hacking effort has been unearthed," Ryan Chittum of the Columbia Journalism Review writes. "The chilling effect on future potential sources is going to make reporting on it that much harder."
