📱 Sherlocked Security – Mobile Application Penetration Testing

Secure Your Mobile Apps Before They Become Attack Vectors

📄 1. Statement of Work (SOW)

Service Name: Mobile Application Penetration Testing
Client Type: FinTech, eCommerce, SaaS, Healthcare, EdTech, Government
Service Model: Manual + Automated Security Testing
Compliance Coverage: OWASP MASVS, OWASP Mobile Top 10, PCI-DSS, ISO 27001, HIPAA, GDPR
Testing Types:

  • Black Box (App-only)
  • Gray Box (App + Auth credentials/API docs)
  • White Box (Source code/Backend access – optional)

🧠 2. Our Approach

🔹 Manual + Tool-Augmented Testing
🔹 API & Business Logic Focus
🔹 Device-to-Cloud Attack Surface Coverage

[Discovery] → [Static Analysis] → [Dynamic Testing] → [API & Backend Testing] → [Exploitation] → [Risk Mapping] → [Reporting & Walkthrough] → [Retesting & Certification]

🧪 3. Methodology

[Kickoff & Scope Definition] → [App Build Collection] → [Static Analysis (Code/Decompilation)] → [Dynamic Testing on Device/Emulator] → [API Testing] → [Exploitation & PoC] → [Risk Analysis] → [Fix Advisory] → [Retest & Certificate]

🚀 7. Engagement Lifecycle (Lead → Closure)

plaintext

1. Discovery Call 2. Requirement Gathering 3. SoW + NDA + Proposal 4. Kickoff & App Access 5. Testing Phase (1–2 Weeks) 6. Draft Report + Feedback Call 7. Final Report Delivery 8. Retest Round 9. Final Certification & Handover

🌟 8. Why Sherlocked Security? (Our USP)

Feature Sherlocked Advantage
📱 Deep Mobile Stack Coverage Android, iOS, Hybrid (React Native, Flutter)
🔍 Code + Runtime Testing Static + Dynamic + Backend/API Testing
📘 Dev-Friendly Reports PoC Driven, Fix-Focused
🔁 Free Retesting One round of revalidation included
💬 Hands-on Dev Support Slack/Teams, code-level guidance
🎓 Security Certificate Issued post successful retest

📚 9. Real-World Case Studies

🔓 Insecure Local Storage: Ride-Sharing App

Issue: Sensitive session tokens stored in plain-text
Impact: Token theft → Account hijack → Fraud
Fix: Implemented secure keystore + session hardening

🧪 API Token Abuse in EdTech Platform

Client: India-based Online Learning App
Findings:

  • Missing token scope validation
  • Broken rate-limiting on course download APIs

Outcome:

  • Delivered prioritized patch roadmap
  • Cleared SOC 2 audit post remediation

🛡️ 10. SOP – Standard Operating Procedure

  1. Kickoff meeting
  2. App build collection + environment details
  3. Define scope (App/API/Backend)
  4. Static analysis of code/app binary
  5. Dynamic analysis on emulator/device
  6. Backend/API abuse testing
  7. Draft reporting + feedback
  8. Final report & walkthrough
  9. Developer fix support
  10. Retest & Certification

📋 11. Mobile App Security Checklist (Preview)

  1. Reverse engineer the application for static analysis.
  2. Analyze app permissions and sensitive data storage.
  3. Test for insecure data transmission.
  4. Inspect inter-app communication security.
  5. Analyze authentication and session handling.
  6. Test for client-side injection vulnerabilities.
  7. Evaluate code obfuscation and tamper resistance.
  8. Review use of cryptographic APIs.
  9. Conduct dynamic testing for runtime behavior.
  10. Test backend APIs consumed by the app.
