Owasp Mobile Security Checker

OWASP Mobile Security Checker

Comprehensive security analysis for Flutter and mobile applications based on OWASP Mobile Top 10 (2024).

Automated Scanners

Four Python scanners cover the most automatable risk categories. Replace <skill-dir> with the skill's install path (e.g. ~/.claude/skills/owasp-mobile-security-checker):

M1 — Hardcoded Secrets

python3 <skill-dir>/scripts/scan_hardcoded_secrets.py /path/to/project

Detects API keys, tokens, passwords, AWS credentials, and Firebase keys in Dart code and config files.

M2 — Dependency Vulnerabilities

python3 <skill-dir>/scripts/check_dependencies.py /path/to/project

Analyzes pubspec.yaml for outdated packages, any version constraints, and known CVEs.

M5 — Network Security

python3 <skill-dir>/scripts/check_network_security.py /path/to/project

Checks HTTP vs HTTPS usage, certificate pinning, Android Network Security Config, and iOS ATS settings.

M9 — Insecure Storage

python3 <skill-dir>/scripts/analyze_storage_security.py /path/to/project

Identifies unencrypted SharedPreferences, plaintext file storage, unencrypted databases, and insecure backup configurations.

Manual Analysis

M3, M4, M6, M7, M8, and M10 require code review. See references/owasp_mobile_top_10_2024.md for Flutter-specific vulnerability patterns, attack flows, and remediation for each category.

Workflow

Is this a comprehensive audit?
├─ YES → Run all 4 scanners → Review JSON outputs → Manual analysis (M3/M4/M6/M7/M8/M10) → Generate report
└─ NO → Continue...

Specific risk category?
├─ M1 → scan_hardcoded_secrets.py
├─ M2 → check_dependencies.py
├─ M5 → check_network_security.py
├─ M9 → analyze_storage_security.py
└─ M3/M4/M6/M7/M8/M10 → references/owasp_mobile_top_10_2024.md → manual analysis

Quick pre-release check?
└─ YES → Run all 4 scanners → Fix CRITICAL and HIGH findings only

Quick Start: Full Audit

# Run all automated scanners from the project root
python3 <skill-dir>/scripts/scan_hardcoded_secrets.py .
python3 <skill-dir>/scripts/check_dependencies.py .
python3 <skill-dir>/scripts/check_network_security.py .
python3 <skill-dir>/scripts/analyze_storage_security.py .

# Outputs produced:
#   owasp_m1_secrets_scan.json
#   owasp_m2_dependencies_scan.json
#   owasp_m5_network_scan.json
#   owasp_m9_storage_scan.json

1. Prioritise by severity — fix CRITICAL and HIGH before release
2. For M3, M4, M6, M7, M8, M10 — see references/owasp_mobile_top_10_2024.md
3. Generate remediation plan with code examples and timeline

OWASP Mobile Top 10 (2024) — Quick Reference

Understanding Scan Results

Common False Positives

• M1: Test/example keys, placeholders like YOUR_API_KEY
• M2: Dev-only dependencies (linters, test tools)
• M5: HTTP for localhost/127.0.0.1 in development
• M9: Non-sensitive data in SharedPreferences (theme preference, language)

Always verify findings in context before flagging as vulnerabilities.

When NOT to Use

• Web application security audits — this skill is mobile/Flutter-specific
• Backend API or server security reviews
• As a substitute for professional penetration testing or a formal security audit
• Projects that do not use Flutter/Dart or pubspec.yaml

Reference Documentation

references/owasp_mobile_top_10_2024.md provides per-risk detail:

• Real-world attack scenarios and examples
• Flutter-specific vulnerability patterns (Dart code)
• Insecure vs secure code examples
• Platform-specific guidance (Android Keystore/NSC, iOS Keychain/ATS)
• Full mitigation strategies
