Zip It Up, Sneak It In - Introduction of apkInspector

Presented at DEF CON 32 (2024), Aug. 9, 2024, 10 a.m. (105 minutes).

apkInspector is a tool designed to tackle Android APKs, helping to uncover and decode the evasive tactics used by malware. It can decompress APK entries and extract detailed information such as entry names and sizes, making it easy to analyze the contents of an app. The tool also processes and decodes Android XML (AXML) files into a human-readable format, all while considering the sneaky evasion tactics that malware might employ. apkInspector is able to also identify specific evasion techniques used by malware to bypass static analysis, providing crucial insights for security analysis. It is built to function both as a standalone command-line interface (CLI) for direct operations and as a library that can be integrated into other security tools, enhancing its utility and adaptability in various cybersecurity environments.
