+# P12 - Active Directory Security Audit
+
+## Context
+
+Offensive security audit of a clinic's Windows domain and Active Directory: penetration testing, vulnerability identification and remediation plan.
+
+## Objectives
+
+- Perform a complete AD security audit
+- Identify exploitable vulnerabilities
+- Demonstrate risks through proof of concepts
+- Propose a corrective action plan aligned with ANSSI/NIST
+
+## Methodology
+
+1. **Reconnaissance**: domain enumeration
+2. **Exploitation**: controlled penetration tests
+3. **Post-exploitation**: privilege escalation
+4. **Report**: vulnerabilities and remediations
+
+## Tools Used
+
+| Tool | Usage |
+|------|-------|
+| **nmap** | Network and service scanning |
+| **enum4linux** | SMB/AD enumeration |
+| **Kerberoasting** | Kerberos ticket extraction |
+| **Mimikatz** | Credential extraction |
+| **BloodHound** | AD attack path analysis |
+
+## Identified Vulnerabilities (Examples)
+
+| Vulnerability | Criticality | Risk |
+|---------------|-------------|------|
+| Accounts with SPN and weak password | Critical | Kerberoasting -> privileged access |
+| NTLM enabled | High | Pass-the-Hash |
+| Unconstrained delegation | High | Identity impersonation |
+| Cleartext passwords (GPP) | Critical | Immediate compromise |
+
