    Can a pixel attack exfiltrate data from air-gapped computers?
    Noise generated by the pixels on a screen can be leveraged to exfiltrate data from air-gapped computers in what is called a PIXHELL attack. A researcher has presented the details of a new attack method for exfiltrating data from air-gapped computers using the noise generated by the ‘pixels’ on the screen.

    How does a pixel attack work?
    The PIXHELL attack works by modulating pixel patterns on the screen to generate acoustic noise in the 0-22 kHz frequency range, which carries encoded signals. Nearby devices, such as smartphones or compromised laptops, can capture these signals and decode them.

    How do you prevent a pixel attack on a computer?
    Jamming or noise generation, where background noise is introduced to disrupt the acoustic signals and increase the signal-to-noise ratio (SNR) to make the attack impractical, is also a solution. Dr. Guri also suggests monitoring the screen buffer with a camera to detect unusual pixel patterns that do not match the system’s normal operations.

    Can pixel-based data exfiltration be used to exfiltrate air-gapped computers?
    A researcher has presented the details of a new attack method for exfiltrating data from air-gapped computers using the noise generated by the ‘pixels’ on the screen. The data exfiltration method, named PIXHELL, was discovered by Mordechai Guri of the Ben-Gurion University of the Negev in Israel.

    How can a Pixell attack be detected?
    In the case of a PIXELL attack, an analysis of the screen buffer can be used to detect the transmission pattern, which usually consists of white pixels on iterative patterns that encode a specific frequency. Such a solution can be implemented at the user or kernel level. For example, utilizing GDI functions to capture the screen.

    What is a Pixell attack?
    The PIXELL attack involves an equal-intensity random signal with a constant power spectrum density of 0-24 kHz. However, such devices’ environmental and health implications can vary by jurisdiction, and they are considered less practical for wide deployment. Spectrum Monitoring.
