# 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 |
|
|
|
|
