They can't reconstruct anything except color spots with unreadable something looking maybe like text.
Read the paper. Article is a clickbait.

QuoteIt's easy too - one could be standing outside a building with an antenna that captures images in real time, or they could plant a device that captures and transmits (or stores) images.

So reading this my primary question was "what is the range of this?"

The answer seems to be a matter of inches. The antenna is nearly touching the monitor itself! See Figure 7 on page 6 of the source pdf research paper.

It's very impressive as a way to undetectably "bug" a display without needing an inline device on the HDMI cable, but it does not work remotely.

The article states that it can pick up from a few meters away. Single is one, couple is two, few is three or four.  1m is 3ft so this is way longer than a few inches.  And if you create a bigger antenna, you create longer range but more interference.  So you're not wrong about the inches thing because it's technically true you can receive signal inches away, but you're wrong because you're thinking small and close-minded.  The CIA can point a laser at your window and hear conversations in the house crystal clear from the vibration.  This is the same thing, slightly different.  And if you can do it on a small scale, you can do it on a large scale but your AI algorithm is going to have to step it up to deal with all that interference.

Looking through someone window with some binoculars could have a much higher success rate. 2 steps verification should provide a much better security than only passwords

At the moment, as real practice has shown, the complete stupidity and irresponsibility of government officials and company employees allows hackers to find new security holes and leak huge amounts of obviously confidential information without any such tricks. It's trivial because the human brain is the most powerful attack weapon in the world...

The world consists of 99% idiots and 1% smart people, who have little to oppose. Only faith in their good intentions...

Researchers have developed an AI-powered method to reconstruct images displayed on a computer screen by intercepting electromagnetic radiation emitted from the HDMI cable. Hackers could remotely capture sensitive information, such as passwords or financial data. While the average user is unlikely to be targeted, organizations handling sensitive information should be aware of this and take necessary measures if needed.
