IoT devices (smart lightbulbs, smart cameras, etc.) will soon be everywhere, allowing us to connect to various devices and perform multiple actions that will make our lives easier. These devices seem to enter the market without much regard for security and while they are offering a range of opportunities for manufacturers and consumers, they also pose major risks in terms of security. This project will focus on designing and implementing attacks against some IoT device, or on defences that mitigate existing attacks, to evaluate its overall security against cyberthreats.
