As modern vehicles evolve into complex networks of software and hardware, they become increasingly susceptible to cyber threats. In this hands-on workshop, we will explore how vulnerabilities in automotive systems can be identified, analyzed, and demonstrated. Participants will dive into real-world scenarios using practical tools and techniques to penetrate vehicle networks, uncover security flaws, and experiment with live attacks. This workshop bridges the gap between theoretical knowledge and practical skills, empowering attendees to better understand the increasingly connected automotive landscape. The session will begin with an introduction to automotive security concepts and the architecture of modern vehicle networks. Participants will then learn how to interact directly with the Controller Area Network (CAN) bus, the central communication system in most vehicles. Through guided, hands-on exercises, they will reverse engineer messages to the instrument cluster and send spoofed signals to manipulate displayed information.
