Description
The physical IoT device of the AliveCor's KardiaMobile, a smartphone-based personal electrocardiogram (EKG) has no encryption for its data-over-sound protocols. Exploiting this vulnerability could allow an attacker to read patient EKG results or create a denial-of-service condition by emitting sounds at similar frequencies as the device, disrupting the smartphone microphone’s ability to accurately read the data. To carry out this attack, the attacker must be close (less than 5 feet) to pick up and emit sound waves.
