AndroidSecurityProject

AndroidSecurityProject is a security-focused analysis and hardening initiative designed to uncover and mitigate vulnerabilities in Android applications. The project demonstrates real-world Android security testing using both static and dynamic techniques, aligned with modern Security Engineering practices.

🔍 Project Overview

This project focuses on evaluating Android APKs to identify critical security flaws such as:

  • Insecure data storage
  • Hardcoded credentials and secrets
  • Misconfigured AndroidManifest permissions
  • Exported and exposed components
  • Insecure network communication (HTTP, weak TLS configs)
  • Debuggable app builds
  • Improper WebView configuration
  • Missing or weak obfuscation

Both reverse engineering and runtime application testing are performed to simulate real attack scenarios and validate exploitability.

🛠 Tools & Technologies

Static Analysis

  • APKTool
  • JADX / Jadx-GUI
  • MobSF (Mobile Security Framework)
  • Android Lint
  • SonarQube (optional)

Dynamic Analysis

  • Android Emulator / Genymotion
  • Drozer
  • Frida
  • Burp Suite (for intercepting traffic)
  • ADB (Android Debug Bridge)

📌 Features

  • Automated APK decompilation and code inspection
  • Manifest permission and component exposure audit
  • Security misconfigurations detection
  • HTTP traffic interception and SSL pinning bypass testing
  • Frida scripts for runtime behavior analysis
  • Reporting of vulnerabilities with CVSS-based severity
  • Secure coding and mitigation recommendations

🧪 Testing Workflow

  1. APK Collection & Environment Setup
  2. Static Code Review & Reverse Engineering
  3. Manifest and Permission Audit
  4. Dynamic Runtime Analysis
  5. Traffic Interception & Encryption Validation
  6. Exploit Attempts (Where Applicable)
  7. Documentation of Findings & Fixes

🔐 Key Vulnerabilities Identified (Examples)

  • Hardcoded API keys in source code
  • Insecure SharedPreferences / SQLite storage
  • Exported activities and broadcast receivers
  • Debuggable flag enabled in production builds
  • Unencrypted network requests
  • WebView JavaScript enabled without restrictions

✅ Mitigations Implemented

  • Enforced secure storage with Android Keystore
  • Disabled exported components unless required
  • Removed hardcoded secrets and implemented secure environment handling
  • Switched to HTTPS with modern TLS configuration
  • Added certificate pinning support
  • Restricted WebView and disabled insecure settings

📄 Deliverables

  • Vulnerability Assessment Report
  • Threat Modeling Summary
  • Code Patches / Hardening Changes
  • Final Security Posture Summary
