To do this, the experts used a simple $ 5 piezoelectric transducer that was attached to the tabletop. To hide what was happening from the victim, the researchers adjusted the volume of the attacked device’s responses using a directed ultrasonic command, but they themselves were still able to record the assistant’s voice responses through a hidden “bug” located under the table.
