"They take a regular human voice and use it to modulate an ultrasound signal, much like the way music can be encoded onto radio waves".
The team claim to have validated the attack experimentally on 16 popular voice controllable systems and seven speech recognition systems.
WHILE voice-activated assistants like Siri and Alexa were created to make our mobile lives easier, hackers can turn it into a complete nightmare by using ultrasonic sounds to take command of your smart phone. Modifying a smartphone to issue such commands costs around $3. You'd also have to have your assistant activated, in the case of Siri or Google Assistant, and if an ultrasonic commanded activated, those systems would make a tone or reply back, alerting the user. They devised a way that hackers could use voice recordings of the device's owner to synthesize the opening voice command using pieces of other words. Siri, Google Assistant, Samsung S Voice and Alexa, across a multitude of devices, are all equally vulnerable. Hackers could use a phrase such as "he carries cake to the city", and slice up the phonemes to create the phrase "hey, Siri". The hacker could then perform a walk-by attack, gaining control of a device without physically touching it, altering the device settings, or installing any malware. Secondly, the device needs to be in a proximity of less than five to six feet.
