Um estudo de ferramentas open-source para perícia forense em dispositivos com Android 14

Abstract

The increasing use of smartphones in the last decade brings with it new problems. The use of mobile devices to store people’s sensitive data creates a new vulnerability to be exploited by adventurers, who now target these devices. With this in mind, this work aims to analyze tools that aim to assist in the investigation of these mobile devices, focusing on the most used operating system, Android. This evaluation is carried out through the study of seven preselected open-source tools, these being: AFLogical OSE, dd, Foremost, LiME - Linux Memory Extractor, AMExtractor, Volatility, IPED System and Avilla Forensics; through practical tests and concrete results, based on experiments and research. The study also demonstrates several challenges and peculiarities encountered when trying to use these tools, as well as guides for easy installation and execution of them. At the end of the work, the tools that, for the most part, had difficulty in successfully performing their function were analyzed. The tool that achieved the best performance, based on the defined criteria, was, finally, AFLogical OSE.
