Digital Forensics Investigation on Samsung A-Series Device
This project focuses on performing a complete digital forensic investigation on Samsung A-series Android devices. The objective was to acquire, extract, and analyze digital evidence using standard mobile forensic methodologies. The investigation involved multiple acquisition techniques including logical and file system extraction to retrieve valuable data such as contacts, call logs, SMS, multimedia files, application data, and location history. Advanced forensic techniques were also used to recover deleted artifacts and analyze encrypted storage areas. Special attention was given to Samsung-specific security features such as device encryption and secure storage, ensuring forensic integrity and adherence to investigation standards. The extracted data was analyzed to reconstruct user activity, identify potential evidence, and generate a structured forensic report. The project demonstrates practical implementation of mobile forensic workflows used in real-world cybersecurity and law enforcement scenarios.
