RAM forensics, also known as volatile memory forensics, involves capturing and analyzing data stored in a system’s ...
Introduction If you have ever examined Android logs, mobile extractions, or application databases, you have likely encountered long numbers such as 1708425600. At first glance, these numbers look confusing. However, they represent one of the most important time formats used in digital systems — the UNIX date, also known as ...
Introduction In digital investigations, understanding what happened is important. However, knowing when it happened is often even more critical. That is where timeline analysis plays a central role. Timeline analysis in digital forensics helps investigators reconstruct events in chronological order. By organizing system activities, file modifications, log entries, and user ...
Introduction In modern digital investigations, device state can determine the outcome of a case. When investigators seize a smartphone or computer, its condition—powered on, powered off, locked, or unlocked—directly affects the data they can access.
