Build an Android Application Pentesting Framework
Design a penetration testing toolkit for Android applications that detects common security flaws through static and dynamic analysis, enabling developers and auditors to secure mobile apps effectively.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.
Static APK Analysis
Decompile APKs to identify insecure components, hardcoded secrets, weak crypto, and logging.
Manifest & Permission Review
Scan for dangerous permissions, exported activities, and misconfigured components.
Dynamic Instrumentation
Inject Frida/Xposed hooks to monitor function calls, bypass root/jailbreak checks, and analyze runtime behavior.
Traffic & API Monitoring
Capture and analyze network traffic for plaintext transmissions, token leaks, or weak authentication flows.
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.
APK Analysis Tools
jadx, apktool, MobSF (optional CLI mode), androguard for static analysis.
Runtime Analysis Tools
Frida, Xposed, Rooted Android Emulator or Physical Device, Termux or Magisk.
Traffic Capture
Burp Suite, mitmproxy, custom CA cert installed in test environment.
Reporting Interface
Flask + React, or CLI-based markdown/PDF exporter with risk scoring.
1. Set Up APK Analysis Engine
Use jadx/apktool to decompile APKs and scan for known risky patterns and misconfigurations.
2. Review Permissions and Intents
Parse AndroidManifest.xml and flag risky or misused components.
3. Instrument Runtime Behavior
Use Frida scripts to observe or alter function behavior in a rooted test environment.
4. Monitor Traffic via Proxy
Run the app through mitmproxy/Burp to observe sensitive data leaks or authentication flaws.
5. Generate Security Audit Report
Summarize findings with severity, CVE references, and remediation suggestions.
Analyze, Exploit, Defend — Secure Android the Right Way
Build a complete Android pentesting toolkit that helps developers, auditors, and ethical hackers secure mobile apps from real-world threats.
