The commercial drone market has significantly taken off for a few years. In 2016, sales of drones used for commercial and enterprise purposes was worth 3.4 billion dollars [3]. This fast-growing field raises many questions regarding security since damages caused by such drones could be disastrous. Knowing that in some cases, transmission range is so wide (7 kilometers for a DJI Phantom 4 Pro) and that some drones can lift off more than 30 kg worth of equipment, we cannot deny that there will be (and already are) unexpected and unwanted uses of such a technology. In this article, we introduce DroneJack, an automatic anti-drone solution that can protect an area from being flown over. Using DroneJack, you can conduct a predefined defense over foreign drones as shutting them down, pilot them instead of the true user, direct them towards some GPS coordinates. You can also exploit data owned by the drone to recover photos, videos or flight logs. Even better, you can configure your own attacks on foreign drones and deploy them on DroneJack. Let's play!
