PIXHELL: Novel Acoustic Attack Exploiting LCD Monitor Noise to Leak Secrets from Air-Gapped Systems - 29d

A new acoustic attack called PIXHELL has been discovered, which can leak sensitive data from air-gapped and audio-gapped systems by exploiting the subtle noises emitted by LCD monitors. This attack can extract secrets without the need for speakers or physical access to the devices. The technique exploits the relationship between the brightness changes on the LCD screen and the associated acoustic emanations. By analyzing the audio generated by the display, attackers can extract the information being displayed, potentially including system prompts and user actions. This novel attack highlights a vulnerability in the security of physically isolated systems and emphasizes the need for organizations to implement comprehensive security strategies, including monitoring for unexpected acoustic anomalies in controlled environments.
