The combination of exFAT mapping scheme with the allocation of bitmap files and the use of FAT leads to new forensic possibilities. The recovery of deleted files, including fragmented ones and carving becomes more accurate compared with former forensic processes. Nowadays, the accurate and sound forensic analysis is more than ever needed, as there is a high risk of erroneous interpretation. Indeed, most of the related work in the literature on exFAT structure and forensics, is mainly based on reverse engineering research, and only few of them cover the forensic interpretation. In this paper, we propose a new methodology using of exFAT file systems features to improve the interpretation of inactive entries by using bitmap file analysis and recover the file system metadata information for carved files. Experimental results show how our approach improves the forensic interpretation accuracy.

In this context, the role of the First Responder for discovery, identification and preservation is considered to be one of the short-term most critical challenge. While the number of devices to be collected was reasonably small and the items were easily identifiable in the past, it is not the case anymore. Many initiatives aim at harmonising technical and legal standards to facilitate electronic evidence exchange, although a consistent approach in basic equipment and training of the field police officer is still missing. Hence, in this paper, we study how synergies between different international organisations create and deploy an innovative and sustainable approach to address capacity building challenges related to the tasks assigned to the First Responder.
