Does that potentially compromise any secure connection, be it SSH, encrypted voice/video call etc. that is established between these computers, or does the encryption (provided it's strong enough) make it impossible to intercept with a physical device on the line? I'd have presumed the latter, because it's no different to trying to hack it from anywhere else, but I might be overlooking a technicality. To clarify, the PC connects to a router that is wired to a wall box serving as an 'entry point' of the connection into the property. Any such bugging device would therefore be placed between the router and the outbound cabling onto the street.
Strong encryption is used these days and the session keys are changed frequently. While theoretically breakable, it would take a huge amount of computer power.
