🎯 Goal
Learn to analyze, secure, and penetration test mobile applications and the devices they run on. Cover both Android and iOS platforms, understanding their security models, common vulnerabilities (OWASP Mobile Top 10), and how to use dynamic and static analysis tools.
🔑 Key Skills to Learn
- Mobile Platform Security Models: Android (permissions, sandboxing, SELinux, verified boot) and iOS (sandboxing, code signing, Secure Enclave, Keychain).
- Application Fundamentals: APK/IPA structure, AndroidManifest.xml analysis, Info.plist, app signing.
- OWASP Mobile Top 10: Improper platform usage, insecure data storage, insecure communication, insecure authentication, insufficient cryptography, code tampering, reverse engineering, etc.
- Static Analysis: Decompiling apps (JADX, apktool, Ghidra for native libraries), reviewing source code, identifying hardcoded secrets.
- Dynamic Analysis: Intercepting HTTP/HTTPS traffic via Burp Suite (proxy setup, certificate pinning bypass with Frida/Objection).
- Instrumentation & Hooking: Frida for runtime manipulation, Xposed modules, Objection for automated bypasses.
- Device Administration & MDM Basics: How mobile devices are managed in enterprises, common security policies.
- Root/Jailbreak Detection Bypass: Understanding how apps detect compromised devices and how to circumvent it.
