here is an example: https://fulldecent.github.io/system-bus-radio/

https://fulldecent.github.io/system-bus-radio/ - Tested on MacBook Air / Chrome with AM tuner at 1560 kHz. See field reports for other equipment and frequencies.

Probably because to get this stuff to work is really hard in practice.

Several years ago, we were playing with https://github.com/fulldecent/system-bus-radio to work, but we couldn't, even though we had the right MacBooks.

Have you gone fully paranoid and your air-gaped system is in a Faraday cage inside an anechoic chamber? Things like bus radio [1], coil whine and power fluctuations can be used (it has been shown) to exfiltrate data.

I should have linked to an internal page that redirected there so people didn't get a misleading 404, but the internal coen repo is only open to Monzo employees not the public because it contains some HSM specific stuff :( sorry - the public coen (which we're a fork of) is open though here https://github.com/iana-org/coen
