Android is the most popular operating system among mobile devices and the malware targeted explicitly for Android is rapidly growing and spreading across the mobile ecosystem. In this paper, we propose a hybrid analysis of Android malware to retrieve evidential data, generated from or accessed by such mobile malware, which can be adopted as critical evidence for civil and criminal cases. We target on Android malware from Joker Family where we collected and analyzed 62 recently discovered malicious apps, we found that: 11 apps access and store user’s location information, 17 apps track user’s SMS text messages and 58 apps send out user personal information to remote servers. Our proposed approach found that, evidence data including location, timestamp, IP address are still able to be identified from the local file system and logging system. Our main contribution in this research is to provide an effective forensic analysis report on Android malware that can extract critical evidence from the local file systems as well as system logs.
