New SmartAttack Technique Uses Ultrasound to Steal Data

A new attack technique, named SmartAttack, has been demonstrated in a laboratory setting. This method allows a potential attacker to steal confidential data by "listening" to the ultrasound produced by PC speakers and intercepted by smartwatch microphones. The technical details of this attack involve using ultrasound to transmit sensitive information, which is then picked up by nearby smartwatches. This technique could pose a new threat to data security, particularly in environments where devices are in close proximity to each other.
