The concept, created by researchers from Ben-Gurion University, sounds like something out of a spy thriller, but the details reveal just how technically complex and narrowly feasible such an attack would be.
The method, dubbed “SmartAttack,” relies on exploiting the microphone of a compromised smartwatch to receive ultrasonic signals from an infected air-gapped computer.
These ultrasonic transmissions operate between 18 and 22 kHz, just above the range of human hearing, and can carry data such as keystrokes or biometric information at up to 50 bits per second over distances of at least six meters.
For any part of the attack to work, multiple difficult steps must already be accomplished. (Whew!) more
