Memory forensics of insecure android inter-app communications

Abstract

Android is designed in a way to promote the implementation of user task flows among multiple applications inside mobile devices. Consequently, app permissions may be leaked to malicious apps without users noticing any compromise to their devices’ security. In this work we explore the possibility of detecting insecure interapp communications inside memory dumps, with forensic analysis results indicating the possibility of doing so across the various layers of Android’s architecture. Yet, for the detailed evidence reconstruction that could be required during digital investigation, current capabilities have to be complemented with evidence collected through live forensics. We propose that this process should still be based on carving forensic artifacts directly from memory.
