PowerLine Truck Hacking: 2TOOLS4PLC4TRUCKS
Introduces two open tools for auditing and testing power-line communications and PLCs in heavy-duty vehicles.
Summary
Automotive security researcher Ben Gardiner delivers a technical deep dive into heavy vehicle power line communications (PLC) in the ICS Village, introducing open-source hardware and software tools to assess commercial trailer network security [00:01, 00:06].
Gardiner explores SAE J2497 (PLC4TRUCKS), the standard that modulates multiplexed digital signals directly over existing 12V tractor-trailer power wiring to control pneumatic anti-lock braking systems (ABS) [08:35]. He details the development of modified "Truck Duck" hardware interfaces utilizing RF up-converters and software-defined radios to overcome bandwidth limitations [17:51, 26:56], analyzing regulatory considerations under FCC unintentional radiator exemptions [36:51] and demonstrating how unauthenticated PLC traffic can be injected to manipulate commercial trailer telemetry [45:41].
