CANToolz is an open-source framework for working with CAN bus. In this presentation we will demonstrate use-cases and examples of black-box analyses of CAN network and ECU devices. This framework based on modules and libraries that can be used all together in different combos to get exactly what researcher/tester needs. 1. What tester could do over OBD2 port?UDS scanning, sub-function scanningTester tool testing and traffic analysis2. CAN Switch/Hub scanningWhat messages could be routed from one bus to another?3. Understanding the trafficHow to find "what means what"Finding control framesFinding status frames4. Running MitMDIY: anti-thief system Also, you could use CANToolz for integration/security tests as part of developing process (SDLC), and we will cover this part as well.
