Android Penetration Testing Cheat Sheet
Overview
The Android Penetration Testing Cheat Sheet is an invaluable resource tailored for cybersecurity enthusiasts and professionals looking to enhance their skills in mobile application security testing, specifically on Android platforms. Created by Ivan Sincek, the project serves as a personal checklist and a repository of knowledge that includes useful tips, tricks, and techniques for conducting penetration testing on Android devices.
System Environment
Testing and development for this cheat sheet were conducted using Kali Linux v2023.1 (64-bit) and a Samsung A5 (2017) running Android OS v8.0 (Oreo) with Magisk root v25.2. For users interested in rooting their Android devices, guidance is provided through links to Magisk, although the author disclaims liability for any resulting actions.
Recommended Reading
To maximize the benefits from this cheat sheet, it is suggested that users familiarize themselves with the OWASP MASTG and OWASP MASVS documentation. These resources provide foundational knowledge crucial for understanding mobile security assessment and testing standards.
Structure and Contents
The cheat sheet is systematically organized to guide users from basic activities to more advanced penetration testing techniques. Below is a brief overview of its key sections:
0. Install Tools
This section provides detailed instructions on installing essential tools such as WiFi ADB for wireless debugging, Magisk Frida, and various tools on Kali Linux for Android application testing. It also covers installation steps for Java, Apktool, the Mobile Security Framework (MobSF), and Drozer, essential for code analysis and exploitation.
1. Basics
Here, users learn the foundational skills involving the use of Android Debug Bridge (ADB) for tasks like installing/uninstalling APKs, transferring files, and overcoming permission restrictions.
2. Inspect an APK
This section focuses on pulling APK files from devices and examining core files such as AndroidManifest.xml for misconfigurations and potential vulnerabilities.
3. Search for Files and Directories
The guide discusses efficient methods for locating sensitive files and directories on Android devices that could hold key information for penetration testing.
Advanced Sections
In-depth topics include the use of Frida for dynamic analysis, analyzing WebViews, dealing with intent injections, taskjacking, tapjacking, and strategies for APK decompilation and repackaging.
Tips and Best Practices
The document provides invaluable advice on security best practices, helping testers not only identify vulnerabilities but also understand the importance of securing Android applications. From establishing unbreakable SSL/TLS communication to managing secure storage of sensitive information, it provides holistic guidance.
Future Plans and Developments
The author plans to expand the cheat sheet with new topics like modifying network security configurations, SMALI code injections, and more Frida scripts, ensuring the resource remains current and comprehensive.
Conclusion
The Android Penetration Testing Cheat Sheet is an essential toolkit for anyone interested in Android application security. It offers a clear, structured path from basic concepts to advanced testing mechanisms, effectively catering to a wide range of users from beginners to professional penetration testers.
