September 10, 2024 at 04:52PM A new method called “Pixhell” can breach air gaps by using sound waves to transmit data via LCD screens. This covert channel attack works by manipulating screen pixels to create sound waves that encode stolen data. High-level security organizations are at risk, though some have built elaborate air gaps to … Read more
September 10, 2024 at 03:29PM A new acoustic attack, ‘PIXHELL,’ has been discovered that can extract information from air-gapped and audio-gapped systems using LCD monitors, without the need for speakers. Based on the meeting notes, the key takeaway is that a novel acoustic attack called “PIXHELL” has the capability to leak secrets from air-gapped and … Read more
September 10, 2024 at 07:39AM PIXHELL, a new side-channel attack, targets air-gapped computers by exploiting the “audio gap” to exfiltrate sensitive data using the noise generated by the screen pixels. The attack doesn’t require specialized audio hardware and could bypass air-gapping security measures. Countermeasures include acoustic jammers and monitoring for unusual signals. From the meeting … Read more
