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 US-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 report also says that China is using its own internet infrastructure to target US government agencies with phishing emails, which are then sent out via email.

The email accounts are un-ciphered, private 'open' accounts (ie gmail, hotmail, yahoo etc).
