MobileSentry 📱🔒

Mobile Application Security Testing Framework — A comprehensive toolkit for Android (APK) and iOS (IPA) application security analysis, static/dynamic analysis, traffic interception, and automated OWASP Mobile Top 10 checks with bypass techniques.

✅ Status: Alpha — All 9 phases complete.

Features

Phase 1 — APK Analyzer ✅

APK Decompilation — Decompile APKs via apktool with directory tree visualization
Manifest Analysis — Extract package name, version, SDK levels, debuggable flag, allowBackup, network security config, signing info
Permission Analysis — List all declared permissions classified by severity (dangerous/normal/signature/custom) with counts
Component Enumeration — Activities, services, receivers, and content providers with export status and intent-filter detection
Security Misconfiguration Checks — 8 automated checks:
- Debuggable flag detection
- Backup enabled vulnerability
- Missing network security config
- Low minSdkVersion targeting
- Unnecessarily exported components
- Excessive permission requests
- Sensitive permission combinations (Camera+Mic, Location+Background, etc.)
Hardcoded Secrets Detection — 23 regex patterns scanning decompiled source for:
- AWS keys, GitHub tokens, Slack tokens, JWT tokens
- Firebase URLs, Google API keys
- Passwords, connection strings, private keys
- OAuth secrets, API keys, and more
Statistics — File counts, DEX classes, native code detection, obfuscation detection, analysis timing
JSON Export — Full structured report for integration with other tools
Rich Terminal Output — Color-coded severity badges, formatted tables, panels, and progress spinners

Installation

⚠️ Note for Kali Linux / Debian 12+: System-wide pip install is blocked to protect the OS. Always use a virtual environment as shown below.

Python Package

# Clone the repository
git clone https://github.com/Yash-Patil-1/mobilesentry.git
cd mobilesentry

# Create and activate a virtual environment
python3 -m venv venv
source venv/bin/activate

# Install MobileSentry (recommended)
pip install -e .

# Or install with extra dependencies
pip install -e ".[analyze]"    # For APK analysis (androguard)

# Generate a JSON report (for CI/tooling integration)
mobilesentry report --apk ./result.json --format json

# Generate a Markdown report (for documentation)
mobilesentry report --apk ./result.json --format md --output ./REPORT.md

The generated HTML report includes:

Permission Analysis

Permissions are color-coded by severity:

🔴 DANGEROUS — Sensitive data access (Camera, Location, SMS, etc.)
🟠 SIGNATURE — System-level permissions
🔵 UNKNOWN — Custom or undocumented permissions
✅ NORMAL — Low-risk permissions (Internet, Network, etc.)

Security Issues

Each issue is displayed in a bordered panel with:

Severity badge (CRITICAL/HIGH/MEDIUM/LOW)
Description explaining the vulnerability
Actionable recommendation

Secrets Detection

Hardcoded secrets are displayed in a table with severity, type, truncated value, file path, and line number.
