Volkswagen Car Entertainment System Forensics

Vehicles are fast becoming another important source of digital evidence in a criminal investigation. Traditionally, when a vehicle is involved in a crime scene (e.g. drink driving), the investigators focus on the acquisition of DNA, fingerprints and other identifying materials, usually non digital in nature. However, modern day cars, particularly smart or driverless cars, store a wealth of digital information, such as recent destinations, favorite locations, routes, personal data such as call logs, contact lists, SMS messages, pictures, and videos. In this paper, we describe some challenges associated with vehicle data forensics, an understudied area. Next, we present our case study on forensic acquisition and data analysis of an entertainment system on a Volkswagen car.
