From a traditional point of view, vehicles used to be closed systems in which components communicated between each other over a central vehicle bus and no connection to remote systems was possible. However, this has drastically changed during the last years with increasing connectivity and autonomy of today’s vehicles. While car manufacturers have a long experience in dealing with safety problems, dealing with security risks raised by this development is a relatively new domain for them.
A training session on Hardwear.io .
For the second year SCHUTZWERK was a sponsor of the hardwear.io conference in Den Haag. This year, we attended the conference with 3 employees focused on hardware and embedded security.
The Training Session One of our hardware specialists, Heiko Ehret, learned how to reverse engineer a microchip in the training IC reverse engineering 101 from Tuesday to Wednesday. In this training the principles of gaining access to the DIE of a chip were presented and in the practical part for example photos, which were taken with a scanning electron microscope (SEM), were analyzed to extract the computational structure as well as reading out the contents of the memories.

While car manufacturers steadily refine and advance vehicle systems, requirements of the underlying networks increase even further. Striving for smart cars, a fast-growing amount of components are interconnected within a single car. This results in specialized and often proprietary car protocols built based on standardized technology.
