Next up, capturing private keys by monitoring the slight power differences in wifi broadcasts. (effectively the same thing, just different wave-lengths of light and you don't need to be as close to it)
The joke was that you're not parsing the wifi frames, you're just looking at infinitesimal changes in the broadcast power/frequency. Of course I don't think this is viable in the real world but in a perfect environment it should work.
It's also just called tempest, it's mostly a nsa thing. They can eavesdrop on crypto from across the street, well that was in the 50s, thats what we learned about 40 years later, god only knows what they can do today.
I would link something, but there isnt even anything useful about it on the internet, that google can find anyway.
