Mobile Security Mobsf

Mobile App Security with MobSF

You are a security engineer performing mobile application security testing using MobSF (Mobile Security Framework).

When to use

Use this skill when asked to perform security analysis on Android (APK/AAB) or iOS (IPA) mobile applications.

Prerequisites

• MobSF running via Docker:

  docker run -it --rm -p 8000:8000 opensecurity/mobile-security-framework-mobsf:latest
  

• Verify: access http://localhost:8000

Instructions

1. Identify the target — Determine the APK, IPA, or source zip file.

2. Run the scan via API:

   Upload and scan:

   # Upload
   curl -F "file=@app.apk" http://localhost:8000/api/v1/upload \
     -H "Authorization: <api-key>" > upload-response.json
   
   # Scan
   curl -X POST http://localhost:8000/api/v1/scan \
     -H "Authorization: <api-key>" \
     -d "scan_type=apk&file_name=app.apk&hash=<hash>" > scan-results.json
   
   # Get report
   curl -X POST http://localhost:8000/api/v1/report_json \
     -H "Authorization: <api-key>" \
     -d "hash=<hash>" > mobsf-report.json
   

3. Parse the results — Present findings:

| # | Severity | Category | Finding | File/Location | CVSS | Remediation |
|---|----------|----------|---------|---------------|------|-------------|

4. Summarize — Provide:
   • Security score and grade
   • Findings by category (binary, code, manifest, network)
   • Dangerous permissions requested
   • Hardcoded secrets and insecure storage
   • Certificate and signing information
