It was more than that. Almost all of the contractors building the place were KGB assets. I had the pleasure of working with the son of the guy that developed the TCSM methods for sweeping for those types of bugs.
There was also a bug that was embedded in the concrete, and would drill a few microns, listen for audio, and if it didn't detect the room audio vibrations it would drill a tad more until it did. Incredible engineering for the time.
