In digital forensics, timestamps are crucial for analyzing key events in chronological order, making them vital to forensic investigations. This paper presents a method for detecting attempts to conceal a crime through the manipulation of timestamps on IT devices. Specifically, we introduce a technique to identify timestamp manipulation in a car’s infotainment system when the suspect's smartphone is connected via Bluetooth. The method involves extracting and analyzing Bluetooth Host Controller Interface (HCI) logs, Bluetooth logs, and system logs from both the smartphone and the infotainment system. Scenario-based experiments demonstrate the effectiveness of this technique in detecting timestamp manipulation on the infotainment system.
