Password Recovery and Data Retrieval in the Android Operating System

Abstract:

This paper considers how data and passwords are recovered across different versions of the Android Operating System (OS). This solution has been achieved by forensically retrieving passwords that were set up in Android 4.4 to 5.0.2. XRY Extraction Wizard and XRY Reader were used as tools to conduct this investigation. The results obtained showed that encryption is the safest method of keeping data secure, while also showing a lack of backwards compatibility with security updates. Android uses a single-use authentication token to authenticate Google accounts, but fails to secure Chrome passwords in the most widely used versions of Android.
