Análise de métodos e ferramentas na investigação forense digital em dispositivos móveis

Abstract

Digital forensic analysis on mobile devices plays a crucial role in information security, especially given the increasing use of smartphones and tablets, which store sensitive data such as credentials, messages, and banking information. This study aims to analyze the methods and tools used in digital forensic investigations, focusing on Cellebrite UFED, Magnet AXIOM, and Oxygen Forensic Detective. The research adopts a descriptive and qualitative approach, including a literature review and document analysis, addressing challenges such as Android system fragmentation, iOS security barriers, and rapid technological evolution. The results highlight efficient practices for the collection and preservation of digital evidence, ensuring compliance with ethical and legal aspects, such as those defined by the LGPD. Furthermore, strategies are proposed to overcome operational and technological limitations, ensuring greater integrity and reliability of evidence. Although current tools offer advanced features, they face difficulties in accessing encrypted data and analyzing recently released devices. It is concluded that the continuous improvement of techniques, tools, and methodologies is essential to meet the increasing demands of the field. This study contributes to strengthening digital forensic practices, providing theoretical and practical insights to help professionals overcome the challenges posed by growing cyber threats and technological diversity.
