SYNOPSIS

As Electronic Control Unit (ECU) quantity and technology become more and more important in a car, with the advent of autonomous and connected vehicles, threats on these vehicles are growing accordingly. While car manufacturers are mainly interested in remote attacks, we will explain through this training that every bit of information can be useful to an attacker, and that both cars security/safety and users privacy could be affected.

The training will be organized around slides explaining the theory of each attack (how it works, how you can use it), and practical sessions to perform this attack on the demo ECU. Practical sessions should take most of the time of the training, and solutions will be provided during each session so that the attendees can learn how to perform each attack.

KEY LEARNING OBJECTIVES

This training presents common attacks against ECUs, as well as several ways to prevent them. This is a hands-on training, so the attendees should expect to perform the attacks by themselves.

We will provide the necessary tools and perform some attacks on a real car.

If most of the exercises will be focused on in-car networks, we will also cover ECU reverse engineering techniques and some radio-frequency flaws.

Special gift : attendees will be given a CAN transceiver and an OBD-II plug to be able to practice their new skills as soon as they come back.
