AI can see your screen by reading HDMI cable radiation

And I cannot post images here without typing ".jpg" at the end of the file URL

The news post https://www.techspot.com/news/104015-ai-can-see-what-screen-reading-hdmi-electromagnetic.html

The paper https://arxiv.org/pdf/2407.09717

So what are your HDMI cables irradiating? Mine mostly posts on Reddit lately and cats.

I don't like those big white monkeys that quote the whole posts instead of just leaving a simple comment.

@imok Maybe this isn't as new a tapping technology as it might seem? Sounds a little like Halibut from the early 1970s.

This kinds of tech exists far more earlier before AI comes, it has a name called Tempest.

https://www.cl.cam.ac.uk/~mgk25/ih98-tempest.pdf

Back in days, people use VGA monitors (signal) to broadcast radio musics by just showing pictures on the screen.

So in current human tech, each electronic signal more or less leaks as radio wave in some format, capture it and play with it you could finally find a way to recover some data of the origin. (AI just makes it easier to be analyzed)

And people use similar idea (it's called side channel attack) cracking hardware AES or other famous cipher.

@imok no problem

Now I want some flan

Wont getting a grounded shielded HDMI cable (which all good hdmi cables are) help with issues like this?

Deep-tempest is such a cool name

Well over a decade ago I saw a presentation of a "ruggedized" laptop with a TEMPEST (Telecommunications Electronics Material Protected from Emanating Spurious Transmissions) of a certain level (the word "NATO" was thrown around, so probably level "A / I" or "full") - stating that it is safe from sniffing for up to one metre of distance (if memory serves me).

Nothing new. Such surveillance (and counter-surveillance) tech. has been out for decades.

Country surveillance at bike levels installing radars,weapons,high tech levels gadgets at bikes during the nightime meanwhile normal IT person during day time FBIkegremlin.com Coincidence????? I do not think so.
