This research assesses the disc imaging, file recovery, artefact analysis, and network monitoring capabilities of open-source forensic tools. Through a detailed assessment, the study finds that while the open-source tools are efficient and possess a wide variety of features, they have limitations in resource efficiency and anti-forensic technique detection. Anti-forensic techniques show a lot of potential in hindering forensic inquiries, creating difficulties in data retrieval and evidential consistency. There is a need for continuous development in forensic technology, especially in improved detection algorithms. By identifying the strengths and weaknesses of existing open-source tools, this study contributes to enhancing the effectiveness of forensic investigations against evolving cyber threats.
