CAN Bus – How Does It Work, and How Is It Attacked?

Realms of Cyber Conference (ROCCON) builds on the success of Brisbane’s previous Autohackers conference. With a vision of enhancing security across various industries – land, air, sea, space, cognitive, and biotechnological – ROCCON is dedicated to making Australia’s digital landscape safer.

At ROCCON 2024 in Brisbane earlier this year, Sekuro RED’s Offensive Security Consultant Sam Kelly delivered an insightful presentation on the CAN Bus network protocol. This ubiquitous networking protocol is integral to modern passenger vehicles, industrial control systems, medical devices, and manufacturing equipment. In his talk, Sam delved into the technical workings of the CAN Bus, explored real-world attack scenarios, and discussed the security measures necessary to safeguard these critical systems.

Below, you’ll find the slide deck from Sam’s presentation, providing a detailed look at his findings and recommendations.
