Samy Kamkar, american businessman, has developed a unique software called “Sky Jack”, which allows a drone operator to take over control of another unmanned aerial vehicle. The program is available on the Internet. In order to hack the control system of UAV, it is necessary to use another unmanned aircraft equipped with a computer on which the “Sky Jack” system is installed. The software can efficiently detect another drone’s Wi-Fi signal, which in turn allows the hacker to take control of the device. The program is capable of detecting drones within 100 meters.
