An expert presented his study on hijacking high-end drones commonly deployed by government and law enforcement agencies. Nils Rodday has found a way to exploit the lack of encryption for the communication between the drone and controller module. A rogue hacker can make a reverse engineering of the drones software components in order to discover which are command accepted by the UAV and send them to the navigation controls. The most worrying part of the research is the scope of the discoveries made by Rodday, many other drones on the market could be affected by the same vulnerabilities.”]
