Wireless Threats Against V2X Communication
Axel Boström, Franz Wotawa
Abstract: As the automotive industry increasingly relies on wireless technologies, a new attack surface emerges, pos- ing significant security threats to modern cars. This paper investigates the vulnerabilities and risks of wireless vehicle attacks, including eavesdropping, message tampering, spoof- ing, and jamming. It highlights vulnerabilities in the CAN bus communication interface. By exploring these attacks and their potential consequences, this paper aims to shed light on the urgent need for robust security measures to safeguard the safety and privacy of vehicle owners. The focus is on under- standing the evolving landscape of wireless threats in the au- tomotive industry, providing valuable insights for researchers, practitioners, and stakeholders involved in developing effective countermeasures and enhancing overall vehicle security. In contrast to other research articles, this paper presents the ISO/SAE DIS 21434 standard, which offers a systematic and structured approach to enhance cybersecurity in the automotive industry, even in the face of emerging wireless threats. In addition, this paper highlights notable examples of attacks on modern cars, where researchers gained access to vehicle systems through wireless vulnerabilities, demonstrating the potential dangers of interconnected car systems to illustrate the real-world implications.
