Researchers can track data from the PC monitor’s luminosity and steal it

Stealing data from Internet or networked computers may not seem so surprising, but now researchers have discovered a way to make that AirGap computer, that is, a computer with no network connected to it. The only way to transfer data can be to steal data by monitoring the monitor’s luminous base, such as USB drives, etc.
Researchers focused a camera on an infected computer’s LCD device and then tracked the changes in the RGB monitor color of the LCD monitor.
