Researchers unveiled a groundbreaking acoustic attack that could pose a major
threat to the security of air-gapped and audio-gapped systems.
threat to the security of air-gapped and audio-gapped systems.
Dr. Mordechai Guri of Ben-Gurion University of the Negev, who orchestrated the
discovery, dubbed the attack PIXHELL. The technique involves manipulating pixel
patterns on LCD monitors to produce acoustic emissions that are impossible to
detect by the naked ear and could leak encoded data.
