Real-time video stream substitution

Abstract

nato’s locked shields1 is an annual live- re cyber defence exercise organised to aid in the training of security experts tasked with protecting national it systems. the scenario-based exercise focuses on the attack and defence of the network and service infrastructure of a ctional country, including military command and control systems, and unmanned aerial vehicles. one such attack performed at the 2017 event focused on the substitution of footage from a military drone’s real-time video feed. the defence network was compromised and the video feed replaced. taking inspiration from the recently concluded event and the attack performed on the drone, this project investigates how a real-time video stream can be seamlessly substituted whilst going undetec- ted. consequently, the investigation will generate the need for further research into uncovered vulner- abilities and their potential solutions.
