Car Hacking Village Vol. 1
A tour of CAN bus test benches, ECU exploitation rigs, and vehicle security research at Car Hacking Village.
Summary
Silk interviews automotive security researchers in the heavy vehicle section of the DEF CON 30 Car Hacking Village, exploring the unique attack surface of commercial trucks and tractor-trailers.
[00:40] The researchers demonstrate how heavy-duty commercial vehicles communicate across specialized protocols, specifically SAE J1939 CAN networks and the SAE J2497 standard (also known as PLC4TRUCKS), which modulates digital diagnostic and control signals onto the vehicle's 12V DC power lines.
[01:16] The discussion explores radio frequency attack vectors against trailer power lines. The researchers explain that the wiring harness acting as a power-line bus is susceptible to external RF interference [01:58], allowing an attacker with a software-defined radio to wirelessly induce messages onto the bus. They illustrate how injecting forged J2497 frames can remotely manipulate trailer anti-lock braking systems (ABS), control auxiliary trailer hardware, and disrupt fleet telematics without physical access.
