Build an Android Application Pentesting Framework

Android apps often carry sensitive user data and have direct access to device-level permissions. A penetration testing framework helps find security flaws in APKs before attackers do — ensuring safe user experience, compliance, and data protection.

This project provides an automated toolkit for analyzing Android APKs, checking for insecure components, exposed services, hardcoded keys, permission misuse, and dynamic runtime flaws through instrumentation and traffic inspection.

The user uploads an APK or provides a package name. The framework decompiles and analyzes its code statically, then sets up instrumentation hooks to run dynamic tests on an emulator or device. It generates actionable reports that highlight the severity and fix recommendations.

• Load APK and decompile using jadx or apktool.
• Scan manifest and code for risky permissions, weak crypto, hardcoded secrets.
• Attach runtime hooks using Frida or Xposed to monitor sensitive method calls.
• Analyze traffic via proxy and identify potential data leaks or insecure endpoints.
• Export findings into a security report categorized by severity and fix strategy.
