TY - GEN A1 - Weiss, Nils A1 - Pozzobon, Enrico T1 - IOT Backdoors in Cars T2 - IT Security Conference Troopers19, 2019, Heidelberg, Germany N2 - Connecting cheap IoT devices to the safety-critical network of a car can be an extremely bad idea, but at least it allows us to hack together our own automotive gadget. This talk explains the complete procedure involved in transforming a cheap OBD GSM dongle designed for fleet management into a open source automotive hacking tool. First, the hardware reverse engineering is demonstrated, showing how each component is interconnected and working together. With this knowledge, it was possible to capture the communication of the GSM module and understand the OTA protocol used by this dongle, which can be used to extract the firmware. A quick reverse engineering of the software will show that no cryptographic authentication is used for the OTA updates, and therefore a pirate GSM BTS can be used to obtain remote code execution. After that, a new open source firmware is written for the device, which can easily be extended and controlled remotely with the LUA scripting language. Examples on how hacking this dongle remotely can affect the safety of the driver will be also given.

All present features of Scapy for automotive penetration will be introduced and explained. Also an overview of higher level automotive protocols will be given. As automotive penetration testing becomes more important, the lack of free tools for automotive network penetration testing led us to integrate new features in Scapy. Scapy is a well established framework for packet manipulation. The flexibility of Scapy allowed us to implement automotive interfaces (CAN) and automotive protocols (ISOTP, GMLAN, UDS, DoIP, OBD-II). This talk explains the basics of these automotive protocols, the workflow with Scapy for automotive network penetration testing. A live demonstration with some embedded hardware will be given.

Now and in the near future, penetration tests in the area of automotive security will still require tools for CAN media access. More and more open source automotive penetration tools and frameworks are presented by researchers on various conferences, all with different properties in terms of usability, features and supported use-cases. Choosing a proper tool for security investigations in automotive network poses a challenge, since lots of different solutions are available. This paper compares currently available CAN media access solutions and gives advice on competitive hard-and software tools for automotive penetration testing.

Technologies like Bluetooth and Internet-connected services found their way into the vehicle industry. The secure implementation of these functions presents a great challenge for the manufacturers because products originating from the consumer industry can often not be easily transferred to the safety-sensitive traffic environment due to security concerns. However, common automotive interfaces like the diagnostics port are now also used to implement new services into the car. With dongles designed to read out certain vehicle data and transfer it to the Internet via the cellular network, the owner can access information about gas consumption or vehicle location through a mobile phone app, even when he is away from the car. This paper wants to emphasize new threats that appear due to the ongoing interconnection in modern cars by discussing the security of the diagnostics interface in combination with the use of an Internet-connected dongle. Potential attack vectors, as well as proof-of-concept exploits will be shown and the implications of security breaches on the safe state of the vehicle will be investigated.
