It's funny you mention that because there was an experiment using case fans powering on and off to signal "morse code" and breech airgapped machines.

Nothing new, just hard to do without endless $$$ supply for research. RAM was never safe and likely never will be.

This applies for all systems right? Not just Intel or AMD?
