How to Take Over Drones
Sebastian Plotz, Frederik Armknecht, Christian Bunse · 2021
The number of unmanned aerial vehicles (UAV) (hereinafter referred to as drone) is rising in both, private and commercial applications. This makes it necessary that a drone remains under full control of the owner at any time. Most drones are controlled wirelessly by protocols in the 2.4 GHz band. The most commonly used protocols are DSMX (Spektrum), ACCST D16 EU-LBT (FrSky), DEVO (Walkera) and S-FHSS (Futaba). While it has been known that the DSMX protocol is vulnerable to attacks, the security of the other protocols was an open question.
