Android Malware Forensics: Reconstruction of Malicious Events

Abstract

Smart mobile devices have been widely used and the contained sensitive information is endangered by malwares. The malicious events caused by malwares are crucial evidences for digital forensic analysis, and the main task of mobile forensic analysis is to reconstruct these events. However, the reconstruction heavily relies on the code analysis of the malware. The difficulties and challenges include how to quickly identify the suspicious programs, how to defeat the anti-forensics tricks of malicious code, and how to deduce the malicious behaviors according to the code. To address this issue, we propose systematic procedures of analyzing typical malware behaviors on the popular mobile operating system Android. Based on the procedures we discuss the deduction of Android malicious events. We also give a real malware forensic case as a reference.
