This method is especially useful when using analog connections such as VGA, HDMI, and DVI.
Researchers have demonstrated that artificial intelligence can decipher radiation coming from a cable several meters away.
To test it, they used software that displayed text on a monitor screen and captured the signal transmitted over the HDMI cable. Then, AI trained on such signals decrypted the intercepted information.
The results showed that 30% of the characters were misinterpreted, but the remaining 70% were sufficient for text recognition.
This technology allows hackers to monitor computer screens and intercept user inputs.
Listening can be accomplished using an antenna outside the building or a device that records signals for further analysis.
