A Weekend Immersed in Hands-On Vehicle Security
A couple months ago, I attended Toyota HackFesta 2025, a two-day Capture-the-Flag event focused on exploring the fast-growing world of automotive cybersecurity. The experience was filled with hands-on learning, collaboration, and challenges that reflected what real vehicle security work looks like.
Exploring Real Automotive Systems Through CTF Challenges
Throughout the event, we worked with three platforms designed to simulate real automotive environments: RAMN, PASTA, and Dumplin.
- RAMN, the Resistant Automotive Miniature Network, is a credit card sized ECU testbed that makes it possible to safely explore how vehicles communicate.- PASTA, the Portable Automotive Security Testbed with Adaptability, offers a flexible and modular environment for analyzing different in-vehicle networks.- Dumplin provides a controlled system that focuses on specific components of automotive cybersecurity.
Each platform taught us how modern vehicle systems operate, how vulnerabilities appear, and how they can be mitigated in real-world scenarios.
Getting Hands-On with RAMN — Why This Tiny ECU Testbed Stood Out
For me, RAMN was the highlight of the weekend. Working with such a compact yet powerful testbed helped me understand how ECUs communicate inside modern vehicles. It allowed me to experiment safely, observe real-time effects of certain actions, and better grasp how weaknesses can be identified and resolved. That hands-on experience made the concepts more tangible and truly sparked my interest in automotive cybersecurity.

Learning from Mentors Who Truly Inspired
The mentors at HackFesta made the experience even more meaningful. They were patient in helping us navigate complex challenges, insightful in the way they broke down difficult concepts, and incredibly passionate about secure mobility. Their encouragement pushed us to think more deeply, approach problems creatively, and gain confidence in our technical abilities.
Collaboration, Community, and a First Place Finish
Throughout the weekend, I connected with like-minded peers who shared the same enthusiasm for learning. I gained valuable knowledge through both the challenges and the collaborative environment. Working with my teammates was energizing, and the effort we put in together led to an exciting outcome. Our team secured first place, which made the entire experience even more unforgettable.
Grateful for the HackFesta Community
I am incredibly grateful to the team at Toyota North America and to the mentors who guided us.
Looking Ahead
HackFesta 2025 was more than a technical event. It sparked a genuine passion within me for automotive cybersecurity. The combination of hands-on exploration, mentorship, and community showed me how technology and security intersect to shape the future of mobility. I am excited to keep exploring and contributing to this evolving field.
