The Car Hacker's Handbook: A Guide for the Penetration Tester
Modern cars are more computerized than ever. Infotainment and navigation systems, Wi-Fi, automatic software updates, and other innovations aim to make driving more convenient. But vehicle technologies haven't kept pace with today's more hostile security environment, leaving millions vulnerable to attack.
The Car Hacker's Handbook will give you a deeper understanding of the computer systems and embedded software in modern vehicles. It begins by examining vulnerabilities and providing detailed explanations of communications over the CAN bus and between devices and systems.
Then, once you have an understanding of a vehicle's communication network, you'll learn how to intercept data and perform specific hacks to track vehicles, unlock doors, glitch engines, flood communication, and more. With a focus on low-cost, open source hacking tools such as Metasploit, Wireshark, Kayak, can-utils, and ChipWhisperer, The Car Hacker's Handbook will show you how to:
- Build an accurate threat model for your vehicle
- Reverse engineer the CAN bus to fake engine signals
- Exploit vulnerabilities in diagnostic and data-logging systems
- Hack the ECU and other firmware and embedded systems
- Feed exploits through infotainment and vehicle-to-vehicle communication systems
- Override factory settings with performance-tuning techniques
- Build physical and virtual test benches to try out exploits safely
Why Read This Book
You will learn how modern vehicles are networked and where their real-world security weaknesses lie, with hands-on techniques for intercepting, analyzing, and exploiting automotive systems. The book combines protocol-level detail (CAN, OBD-II, infotainment stacks) with practical toolchains and lab recipes so you can reproduce attacks and develop mitigations safely.
Who Will Benefit
Security researchers, penetration testers, embedded/firmware engineers, and IoT/automotive developers who want practical, hands-on knowledge of vehicle internals and attack/defense techniques.
Level: Intermediate — Prerequisites: Basic electronics and serial communication concepts, comfort with the Linux command line, and basic programming/scripting (Python or C). Familiarity with microcontrollers, networking fundamentals, and serial debugging will help you get the most from the book.
Key Takeaways
- Analyze vehicle networks and protocols (CAN, OBD-II, LIN, and higher-level gateways) to identify attack surfaces
- Intercept and manipulate in-vehicle traffic using hardware (ELM327, CAN interfaces, Bus Pirate) and software (SocketCAN, can-utils, Wireshark)
- Extract and reverse-engineer ECU and infotainment firmware using JTAG/SWD, SPI/NOR flash techniques, IDA/Ghidra and binwalk
- Exploit common weaknesses to demonstrate attacks (door unlocking, ECU reprogramming, telemetry spoofing) and assess risk
- Fuzz and harden automotive interfaces with practical fuzzing strategies and defensive recommendations
- Build a safe, repeatable car-hacking lab and follow legal/ethical guidelines for responsible disclosure

How It Compares
More hands-on and automotive-specific than general reverse-engineering books like 'Practical Reverse Engineering', and far more attack-focused than standards- or theory-heavy texts on automotive cybersecurity.
