Drone signals discovery involves scanning a network range of endpoint addresses and ports on a UAV or MAVLink-compatible device to discover open ports and active services. Typically this technique requires an attack to be on the same wireless network as the GCS and Drone data-link. This process helps in understanding the UAV's network interface setup and identifying potential entry points for further analysis or penetration testing. Drone systems that use MAVLink can choose arbitrary ports for communication. However, there are several commonly used UDP ports within the drone and ground station software ecosystems. These ports are often used for various purposes such as telemetry, Ground Control Station (GCS) communication, and inter-vehicle communication. (14550, 14540, 14560, 14580, 5760, 5762, 5763)
