*edit: i have the weirdest boner right now

"Over the years, Dr. Guri has concocted various mechanisms to extract confidential data from offline networks by taking advantage of Serial ATA cables (SATAn), MEMS gyroscope (GAIROSCOPE), LEDs on network interface cards (ETHERLED), and dynamic power consumption (COVID-bit).

Some of the other unconventional approaches devised by the researcher entail leaking data from air-gapped networks via covert acoustic signals generated by graphics processing unit (GPU) fans (GPU-FAN), (ultra)sonic waves produced by built-in motherboard buzzers (EL-GRILLO), and even printer display panels and status LEDs (PrinterLeak)."

The nice thing is that a lot of environments that are secure enough to decide to airgap systems these days also make infecting the system and even moreso retrieving the emissions really difficult. Still a really cool field though and I'm glad this Dr. Guri is getting real weird with it.

Okay, that's scary. I'm not a target by many stretches, but this is pretty serious.

For anyone who (unlike me, who hasn't started yet) has completed some kind of qualification in cybersecurity: would it be better to use Faraday rooms/cages, or to revert to pen and paper (with old-fashioned cryptography, if necessary)?

Highly specific attack but certainly looks like it could be effective.

Is this similar to van eck phreaking but reading the ram radio signal instead of the system power draw?

Wouldn't the easiest remedy just be to use adequate shielding around sensitive systems? Is there a reason this would be too difficult?

Its surprising to me how many people have apparently never heard of TEMPEST.

So much for having a dangerous ai just air gapped, I bet living in a computer would let you come up with stuff a human never could
