Explore Android device security research techniques using a diverse device cluster in this conference talk presented by Joshua J. Drake at 44CON Information Security Conference. Learn how to address the "fragmentation" challenge in the Android ecosystem by creating a heterogeneous cluster of devices for more effective auditing and exploit development. Discover the speaker's approach to examining similarities and differences between devices, testing research findings, and extracting specific information. Gain insights into the motivation behind this method, the process of assembling a "droid army," and the tools used for analysis. Witness demonstrations of the setup, including comparisons between devices and automation techniques. Understand the implications of Android's diversity on security research and how this innovative approach can enhance vulnerability discovery and analysis in the world's leading smartphone operating system.
