In 2006, the U.S. Food and Drug Administration approved full radio-frequency based implantable devices operating in the 400MHz range, Jack said at the time .
With that wide transmitting range, remote attacks against the software become more feasible, Jack said. Upon studying the transmitters, Jack found the devices would give up their serial number and model number after he wirelessly contacted one with a special command .
With the serial and model numbers, Jack could then reprogram the firmware of a transmitter, which would allow reprogramming of a pacemaker or I C D in a person’s body .
