In recent years, research and hacking verification experiments have been conducted on cybersecurity countermeasures in vehicles. However, establishing digital forensics technology related to vehicle hacking remains a problem for clarifying the facts, methods, and effects when hacking via an in-vehicle network actually occurs. Digital forensics refers to the methods and procedures for handling digital information recorded on digital devices or elsewhere without loss of evidentiary value, and is regarded as important by various law enforcement agencies, including the police. Some vehicles are already fitted with an event data recorder (EDR) that records the vehicle state, and digital forensics is performed on the EDR when a vehicle accident occurs. The present study surveyed and performed experiments on EDRs, and verified that information related to evidence of hacking can be obtained in addition to conventional information about a traffic accident. Furthermore, this paper discusses security measures for the EDR are discussed from the perspective of performing digital forensics.
