The steps on this askubuntu answer https://askubuntu.com/a/1340029 were almost complete but I had to do a little bit of config file setup with extra instructions from the Arch wiki (https://wiki.archlinux.org/title/PipeWire).

Tested on Ubuntu 21.04+

Steps:

sudo add-apt-repository ppa:pipewire-debian/pipewire-upstream
sudo apt update

CAN Bus Reverse Engineering Challenge #2: Find the Door Unlock Message

Prove it! Find the “unlock” message to gain access to the car!

Background:

Unlocking the doors through CAN message injection is the "hello world" of car hacking. Different vehicles have varying numbers of CAN buses, and send different messages on those buses. The number of messages sent on the vehicle bus make it seem overwhelming to identify which message will help you achieve your goal, but if you have physical access to a vehicle you can find the right message by:
