A 'top-secret' briefing made by the NSA last year reveals that a Chinese hacking group (dubbed 'Dancing Panda') has been accessing the private emails of top U.S.-officials for many years, and that as of the time of that briefing (Q3-14) they were still busily harvesting content. Google had first reported the issue in 2011, but apparently other email providers have confirmed the same type of intrusions. The email accounts are un-ciphered, private 'open' accounts (ie gmail, hotmail, yahoo etc).
