PIXHELL Attack Allows Air-Gap Jumping via Noise From Screens
September 11, 2024 at 09:06AM Researcher Mordechai Guri introduced the PIXHELL data exfiltration method, exploiting monitor noise to bypass air-gapped computers. This approach, along with other air gap-jumping techniques, poses security threats. Malware manipulates LCD screen pixels to emit sound waves encoding sensitive information. The attack can transmit data at a rate of 5-20 bits … Read more
