Yeah,
Story I heard, sorry if i get any specifics wrong. Back in the 80s or 90s, either the USSR or Russia gifted the US a specific and new building to use as the US embassy. The US security services did the best sweep they could, pulled out a ton of bugs, but the conclusion was that the building had been built for spying, with spyware wired deep in the walls, and there was no way to guarantee that they could get it all out. Designed to be a security risk.
Russia set this up.
