In recent years, the automotive industry has witnessed remarkable technological advancements. Modern vehicles have become increasingly connected and autonomous, serving as the cornerstone for the development of Cooperative Intelligent Transportation Systems (C-ITS) and the implementation of future Smart Cities. This necessitates the employment of hundreds of Electronic Control Units (ECUs), a growing number of in-vehicle Cyber-Physical Systems (CPS), and the adoption of new wireless communication technologies that support the deployment of Vehicular Ad-Hoc Networks (VANETs). This phenomenon has garnered the interest of researchers worldwide who have conducted various case studies on unaltered passenger vehicles, demonstrating the feasibility of remotely compromising safety-critical ECUs.
