Cryptography is real, but nobody in that field seems to be hubristic enough to think their methods are flawless, and there's a degree of suspicion than the best models may have secret weaknesses engineered into them by the governments who sponsored them. Physics is real and networking requires a substrate. But there are already known exploits which can misuse the compute hardware as an antenna, e.g. my first search result: https://github.com/fulldecent/system-bus-radio (Older nerds may remember https://en.wikipedia.org/wiki/Van_Eck_phreaking) > Magic is not real Turning lead into gold isn't the magic of alchemy, it's just nucleosynthesis. Taking a living human's heart out without killing them, and replacing it with one you got out a corpse, that isn't the magic of necromancy, neither is it a prayer or ritual to Sekhmet, it's just tra

I got my laptop to play Taylor Swift on the AM band - https://www.youtube.com/watch?v=KH9yb1qFKDY by twiddling the memory bus (sounds a bit iffy ;) Code: https://github.com/anfractuosity/musicplayer Based on the work of https://github.com/fulldecent/system-bus-radio

Modern CPUs can produce an AM radio signal too https://github.com/fulldecent/system-bus-radio

Absolutely: "System Bus Radio" https://github.com/fulldecent/system-bus-radio

If the network is down...Carry on. The music can't stop. "System Bus Radio" https://github.com/fulldecent/system-bus-radio

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. [1] https://github.com/fulldecent/system-bus-radio

Thanks for sharing. You are welcome to add to the TEST-DATA file. We just received the first field report of success with the M1 MacBook Pro here https://github.com/fulldecent/system-bus-radio/blob/master/T...

Oona Räisänen has an awesome video of van eck phreaking against HDMI: https://www.youtube.com/watch?v=BpNP9b3aIfY Also I think this paper is amazing - http://s3.eurecom.fr/docs/ccs18_camurati_preprint.pdf "The well-known electromagnetic (EM) leakage from digital logic is inadvertently mixed with the radio carrier, which is amplified and then transmitted by the antenna. We call the resulting leak “screaming channels”" You might find this interesting too, leaking AM emissions from a computer by twiddling the memory bus - https://github.com/fulldecent/system-bus-radio I made a silly program to play .wav files based on that.

USB serial dongle? pah, use the system-bus on the motherboard ;) https://github.com/fulldecent/system-bus-radio
