🧠 2. Our Approach (with Visual)

🔹 Real-World Attacker Simulation
🔹 Zero-Day & Known CVE Detection
🔹 Deep Reconnaissance + Exploitation

Visual Flow:
[Passive Recon] → [Asset Discovery] → [Vulnerability Scanning] → [Manual Exploitation] → [Risk Mapping] → [Reporting & Retesting]

Color Code:

  • Recon: #064d52
  • Attack: #8b0505
  • Closure: #0f5c5a

🧪 3. Methodology (with Visual)

plaintext

[Kickoff] → [OSINT & DNS Recon] → [Subdomain Enumeration] → [Port & Service Scanning] → [Banner Grabbing] → [SSL/TLS Checks] → [CVE Identification] → [Manual Exploitation] → [PoC Capture] → [Reporting & Retesting]

Visual Key:

  • 🔹 Blue: Information Gathering
  • 🔸 Red: Exploitation & Validation
  • ✅ Green: Reporting & Closure

1. Intro Call → 2. Scope Finalization → 3. SoW + NDA → 4. Asset Enumeration → 5. Testing Phase (3–7 Days) → 6. Draft Report → 7. Fix Walkthrough (Optional) → 8. Final Report + Certification

🌟 8. Why Sherlocked Security? (Our USP)

Feature Sherlocked Advantage
🌐 Deep Recon & Asset Fingerprinting Uncover hidden & legacy assets
🧪 Exploitation-Focused Validate vulnerabilities, not just detect
📘 Dev/Infra Friendly Reports PoCs, Fixes, CVSS Scores included
🔁 Retest Included Confirm patch effectiveness
⚙️ Live Support Fix guidance via Slack/Teams
🎓 Certification Issued post-secure validation

📚 9. Real-World Case Studies

🔓 Forgotten Admin Portal → Full Takeover

Issue: Unlisted admin panel on subdomain
Vuln: Default creds + outdated PHP version
Impact: Remote command execution
Fix: Auth added + infra isolated + version upgraded

🧪 S3 Bucket Misconfiguration

Client: SaaS Startup
Finding: World-readable S3 bucket exposing internal docs
Outcome: Bucket permissions tightened + audit rules added
