Forensics on Twitter and WeChat Using a Customised Android Emulator
Songyang Wu, Wenqi Sun, Xin Liu, Yong Zhang · 2018
Public reports show that crimes linked to social networks have increased sharply in past years. The social networking activity records extracted from a suspect's mobile device plays an important role in the investigation. However, previous works mainly conducted forensics by extracting electronic evidence that is cached in mobile devices and may be deleted for various reasons. In this paper, we proposed a novel investigating approach on Twitter and WeChat based on a customised Android emulator, which can collect evidence from both local device and remote online services. Our approach was evaluated using data copies of Twitter and WeChat from different Android smartphones, which validated the practicability of the proposed method. This paper is intended to provide vital references for the investigators and researchers working on the digital forensics.
