And someone thought hard about it and realized you can hear CPUs at work... In the analog realm...

And decrypted 4096-bit RSA encrypted data by listening to a laptop CPU with a parabolic mic at 13 feet away.

So much for that whole Apple thing. Won't matter for long now. Won't take much to work this tech into something much easier to use.

And that whole microphone that's always on right there next to the CPU thing... Yeah...

Still in its infancy, but that won't last long.
 
We already breached the air gap with speakers (and just hard drives) years back! This just means even more sound proofing for secure nets...
