New Air-Gap Attack Uses MEMS Gyroscope Ultrasonic Covert Channel to Leak Data

A novel data exfiltration technique has been found to leverage a covert ultrasonic channel to leak sensitive information from isolated, air-gapped computers to a nearby smartphone that doesn’t even require a microphone to pick up the sound waves.
Dubbed GAIROSCOPE, the adversarial model is the latest addition to a long list of acoustic, electromagnetic, optical, and thermal approaches devised by
