Hackers Can Spy on Screens Using HDMI Radiation and AI Models

You may feel safe behind your screen, but it turns out that privacy might be more of an illusion than a fact. New research reveals that hackers have found an alarming way to peek at what’s happening on your display—without ever touching your computer. By tapping into the faint electromagnetic radiation that HDMI cables emit, they can now “listen in” on your screen and reconstruct what’s being shown with startling accuracy. 

Here’s how it works: when digital signals travel through HDMI cables from your computer to a monitor, they unintentionally give off tiny bursts of radiation. These signals, invisible to the naked eye, can be picked up using radio antennas or small, discreet devices planted nearby. Once captured, advanced AI tools get to work, decoding the radiation into readable screen content. 

The results? Up to 70% accuracy in reconstructing text—meaning everything from passwords and emails to private messages could be exposed.

This new technique represents a serious leap in digital espionage. It doesn’t rely on malware or breaking into a network. Instead, it simply listens to the electronic “whispers” your hardware makes. It’s silent, stealthy, and completely undetectable to the average user. 

Worryingly, this method is already reportedly in use against high-profile targets like government agencies and critical infrastructure sites. These organizations often store and manage sensitive data that, if leaked, could cause major
