Nowadays almost every vehicle has OBD (On Board Diagnostics) interface. It is most commonly used for car maintenance. We researched Bluetooth adapter usage (read data like RPM or vehicle speed) and security of OBDuditself.

We managed to get the data we mentioned before. On the contrary OBD is knownudto have several (possibly deadly) vulnerabilities, for example someone being able to accelerate or apply brakes remotely.
