Smartphone forensics & data acquisition
This study, both on a theoretical and a practical level, addresses the field of Digital Forensics as far as mobile devices are concerned and specifically the safety of Smartphone devices, which use the operating system of Androids (Mobile Android OS). Smartphone devices are evolving rapidly and their technology and usability outweigh their predecessors. However their main weakness is security. For the operation of Smartphone devices the activation of defense mechanisms is required in order not to become vulnerable to attempts at tampering or eavesdropping. In addition support measures should be taken in order to improve their existing security. One of the most basic and most popular Mobile OS operating systems is that of Android, which was selected and is the basis of this study. The operation of both Smartphone devices as well as Android devices poses major safety issues and therefore protection measures both at user level and at the level of application are required. Moreover, desktop and mobile devices give us the opportunity to recover personal and non personal data from a user. In this case, a series of Mobile Forensics Applications non-commercial are briefly listed and aim at recovering data from Smartphone Devices that run with the operating system Android. Finally, to better carry out the final part of the research three practical scenarios were applied. The first scenario is associated with Mobile Forensic non commercial application, the second with Mobile Forensic commercial application and the third with Mobile Forensic non-commercial Tool. The basic aim is to recover the credentials (Username & Password) of the user from various applications (applications) of Smartphone device.
