Backdooring Hardware Devices by Injecting Malicious Payloads on Microcontrollers, by Sheila Ayelen Berta

Throughout the years, many studies have been published addressing different ways of backdooring devices by leveraging on their own hardware components. However, most of the existing work focuses on backdooring devices based on powerful microprocessors — such as ARM, Intel or AMD — instead of microcontrollers.

Is targeting microcontrollers worth the effort? Nowadays, they are responsible for controlling a wide range of interesting systems, e.g., physical security systems, car's ECUs, semaphores, elevators, sensors, critical components of industrial systems, some home appliances and even robots.

In this talk, it will be explained how microcontrollers can be backdoored too. After a quick review of basic knowledge about uC, we will dive into three different approaches to achieve payload injection, from basic to advanced techniques.
