Greg Hogan - Reverse Engineering and Flashing ECU Firmware Updates - DEF CON 27 Car Hacking Village

Many ECUs do not support reading firmware over CAN, but since automotive manufacturers make mistakes and need to fix firmware bugs, they release firmware updates and support writing firmware over CAN. This will be a deep dive into how you can obtain these firmware updates, decrypt them, (modify if you like) and flash a firmware update file for Honda ECUs. The ECU tools provided by automotive manufacturers are from the stone age, so let’s use a modern web browser to flash an ECU!

Thank You for Your presentation . It was very thoughtful I learned a lot.
Of course I am always wondering how little interest is showed to such a high level
of knowledge . Thanks again .

FYI your dash lit up like a Christmas tree @25:49 because When you flash the ECM (Engine Controller) you take it offline from the CAN bus.
All of the other modules (HVAC / anti lock bakes / Steering..... ) All rely on messages from the ECM.
When they stop getting those messages they freak out.

OMG background noise

Why do all people talk in the background while you hold a presentation? That is disrespectful.
