It analyses the electromagnetic signature of a software set like a virus and they leave a fingerprint that can be traced to a particular virus.

It's like there is a bird song produced by comps when stuff runs. I have heard that myself, hooking up computer chips to audio amps just to hear what they sound like.

Interesting sounds. I guess you can analyze the birdsong and figure out what virus is doing it.

@sonhouse

I didn't read the article but can it trace the starting point of the virus?

Obviously impossible now but that tech needs to be created.
Like a super computer that watches over the entire internet 💪

No, I think this technique is like collecting bird songs. 2 chirps followed by shhhing sound= virus but not where it starts or ends.

@Contenchess
I wonder if quantum computers can do that job?
