Symbian Smartphone Forensics: Linear Bitwise Data Acquisition and Fragmentation Analysis
In this paper, we propose a forensics evidentiary acquisition tool for the Symbian smartphones. We design and build the acquisition tool to support a low-level bit-by-bit acquisition of the phone’s internal flash memory, including the unallocated space. After acquiring the raw image of the phone’s memory, we conduct experiments and analysis to perform a detailed study of the fragmentation scenarios on the Symbian smartphone. The objective of this work is to create a complete evidentiary data acquisition tool for the Symbian smartphone, analyse the latest Symbian OS version, S60 5th Edition smartphone (i.e. find out how user’s data files are being stored on the phone) and to provide a better understanding for the purpose of further in-depth mobile phone forensics evidence reconstruction and security analysis.
