OPEN SOURCING AUTOMOTIVE DIAGNOSTICS presented at BlackhatAsia 2017

by Eric Evenchick,

Summary : Automotive systems use a small number of protocols for diagnostic functionality. As researchers, it's very useful to be able to interact with these protocols to look for undocumented features and vulnerabilities. As vehicle owners, it's useful to have access to these protocols, as they implement all the diagnostics needed to repair a modern car.
The problem? There's no low cost tools for dealing with these protocols. Furthermore, the protocol specifications aren't free. While we can't release the specifications, we can release an open source implementation!
In this talk, we'll go over how automotive diagnostics work, and why they're so interesting for attackers. Then, we'll present an open source Unified Diagnostic Services (ISO14229) stack implemented in Python. Finally, we'll have some demos of how to use the stack in a Python interpreter, to quickly explore diagnostic systems.
