<p>  </p> <p>With the Internet of Things (IoT) development, vehicles have become an essential part of this data transmission network. In order to access the vehicle's status via personal mobile devices, an increasing number of car manufacturers have began to provide mobile applications; some third-party companies offer Bluetooth adaptors for the On-Board Diagnostics-II (OBD-II) port on vehicles made post-1996 in the United States. By connecting the smartphone and the vehicle with either of these methods, the mobile applications can retrieve detailed data and the history of the vehicle. This research aims to answer what forensically relevant artifacts can be recovered from the MB Companion, FIXD, and Nonda ZUS applications. The research methods include adapting the National Institute of Standards and Technology (NIST) forensics framework, generating mock user data, extracting user data, and conducting in-depth digital forensics analysis. The recovered geolocation data, the vehicle-related artifacts, the applications on different vehicle brands, and the applications on various device platforms are primarily examined in the research.</p>

I moderna bilar lagras ofta data från användaren av bilen då en mobiltelefon eller annan enhet parkopplas genom Bluetooth- eller USB-anslutning. I de fall dessa data innehåller personuppgifter kan de vara intressanta i en utredning samt vara värda att skydda ur ett integritetsperspektiv. Vad händer med dessa data då bilen skrotas? När en bil skrotas monteras den ner och de delar som går att tjäna pengar på säljs av bildemonteringsföretaget. Det kan gälla allt från stötdämpare, hjul och rattar, till elektroniska komponenter och multimediaenheter. I detta arbete utvanns personuppgifter ur tre sådana begagnade multimediaenheter som köpts från bildemonteringar. Den mest framgångsrika metoden var att avlägsna rätt lagringskrets från multimediaenhetens kretskort och utvinna dess data genom direkt anslutning. I samtliga fall har informationen varit strukturerad i ett bekant filsystem vilket kunnat monteras. I alla tre undersöka multimediaenheter utvanns personuppgifter. Resultatet visar att det finns brister i hanteringen av personuppgifter då en bil skrotas. / In modern vehicles, data from the user of the vehicle is often stored when a mobile phone or other device is paired through Bluetooth or USB connection. In cases where this data contains personal data, they may be of interest in an investigation and may be worth protecting from a privacy perspective. What happens to this data when the car is scrapped? When a car is scrapped, it is dismantled and the parts that can be made money from are sold by the scrap company. This can be anything from shock absorbers, wheels and steering wheels, to electronic components and infotainment devices. In this report, personal data was extracted from three such infotainment devices purchased from scrap companies. The most successful method was to remove the correct storage circuit from the infotainment device circuit board and extract its data by direct connection. In all cases, the information has been structured in a familiar file system which could be mounted. In all three investigated infotainment devices, personal data were extracted. The result shows that there are deficiencies in the handling of personal data when a car is scrapped.
