Študija varnosti OBD Bluetooth adapterjev

MIRT, ROK (author), Bulić, Patricio (mentor)

Dandanes imajo že skoraj vsi avtomobili vmesnik OBD (On Board Diagno- stics). Ta se običajno uporablja za odkrivanje napak v vozilu.V tem diplom- skem delu smo raziskali možnosti uporabe Bluetooth adapterja za komuni- kacijo z OBD ter varnost samega OBD. S pomočjo mobilne aplikacije smo poskušali prebrati standardne OBD podatke, kot so recimo hitrost vozila, število obratov motorja, itd. Raziskali smo tudi kako je s stabilnostjo takega adapterja in tudi samega OBD. Z adapterjem ni bilo večjih težav, razen občasnih izpadov povezave. Preko OBD nam je uspelo pridobiti podatke, ki smo jih omenili zgoraj. O OBD pa je odkritih že precej ranljivosti, nekatere so zelo resne, na primer možnost oddaljenega pospeševanja, ali izklop zavor.

• Title: Safety of the OBD Bluetooth adapters: a case study

Abstract

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 OBD itself. We tried to read standard OBD data (vehicle speed, RPM...) using mobile app. We researched the adapter stability, as well as OBD’s. There were some minor issues with adapter (dropping connection). We man- aged to get the data we mentioned before. On the contrary OBD is known to have several (possibly deadly) vulnerabilities, for example someone being able to accelerate or apply brakes remotely.
