Doesn’t matter if there was Unclassified information on that network, or Classified information, the gate to that network should never have been left open by someone in the White Hut to be open to the Chinese.
Of course it matters whether there is classified information on an unclassified network.
If there is, then someone screwed up, or did a willful act of espionage.
An unclassified network does have the “gate” open to the outside world, that’s how business is done today.
But to imply, as this blog post does, that nuclear command and control is done on the very same network that is used for email and routine administrative functions is just ludicrous, no matter how many unnamed sources the author cites.
There’s a big, big difference between the “White House Military Office” and a branch of the DOD such as the US Strategic Command (formerly the Strategic Air Command). The office that was hacked is responsible for “military support for White House functions, including food service, Presidential transportation, medical support and emergency medical services, and hospitality services” (quote from Wikipedia).
These are NOT the people who are responsible for the nuclear football, or any aspect of nuclear command and control, and the blog author is irresponsible and factually incorrect to state otherwise.
