Consider that the CIA's internal policy is to treat every computer you touch as if it's been compromised. Even the ones at your desk in the CIA.

Remember that airgapped, inside a Faraday cage computer deep in the vault in Mission Impossible where that analyst was typing a report? They really have those buried away for the Uber Top Secret, don't give this to Russia/China stuff.

So, if even the spy agencies don't trust anything here at home, you think they might know something we don't. Trust nothing, it's all already compromised, seriously.
