This repository contains tools and resources for CAN hacking.

The src folder contains canframe.py that provides the CANFrame class that generates the bitstream of a CAN frame.

Also included are canhack.h and canhack.c, the generic C for the CANHack toolkit. The subfolder pyb contains files that port the toolkit to the PyBoard and make the API available in MicroPython. To patch the MicroPython firmware, also ports/stm32/Makefile and ports/stm32/modpyb.c need editing to build the files and include the CANHack class.

There is a CANHack toolkit demo video that goes into detail on how to use the toolkit, the CAN protocol hacks it includes, and demonstrates it attacking CAN frames in real hardware.

There is also a blog post describing the CANHack toolkit.
