AI can see what's on your screen by reading HDMI electromagnetic radiation

[Squid Surprise]

Nothing to do but try the SDR method described above in the linked keyword Technique. While stocking a nicer GPU for their ML decoder so it's not a whole minute for stuff to get visible. HDMI is TMDS encoded so any change-ups for displayport should be configured... Take that,

"I don't know" would have sufficed instead of being snarky...

You’ll note another user actually answered my question…

It's unclear to me how they'd get passwords by regenerating the display. If the app is showing your password as you type it then you've got bigger things to worry about. Wouldn't they do better putting in a key logger or monitoring Bluetooth signals? Bluetooth should have a much greater range anyway.

This would work in combination with other hacks.... if you've got a screen capture of a login/website, it's a simple matter to search through a previously captured password list and see if you get a matching password... or simply dictionary attack (again using easily available pw lists).

This is why those who argue "what use is a password without the login?" are fools... hackers rarely simply try one thing...

Don't need AI for that.

I remember some researchers discovered this 10 years ago, not only you can hack displays but also read keyboard keystrokes, didn't use AI for that back then and I believe CIA/MI6 have been both using this exploit in the wild.

Maybe they should use fiber optics.

Maybe they should use fiber optics.

For what? Ethernet? How does that help protect display cables?

Fiber optics has no EMI signature and is completely secure to wiretaps, not being electronic signals but light signals. Also, DVD players use lasers, I.e. Blueray. Anything made of metal has this problem, reason being the atmosphere itself is a conductor of electronic signals.
