So they don't actually know what this network is, just who owns the IP space... time for a blog post to advertise our week-old service!

There is no evidence that physically ties this to the WH. It could be in a security lab for all they know. Or a guest network for the news media.

They don't need to be physically inside a specific building to be a networking security problem.

The core issue is whether an outsider has bypassed your firewall and can send+receive traffic from a node which is getting more trust than it deserves. If they've compromised the computer's microphone/camera/wifi-control that's an additional problem.

"We don't know where the devices that appear to have breached the WH network are located. For all we know, they could be in Beijing or Moscow."

That seems significantly worse.

Perhaps ping time measurements could help identify where the devices are physically located.
