Phase 3: Deep Enumeration & Privilege Escalation (60 minutes)

# ✅ Comprehensive Domain Analysis
bloodhound-python -d domain.local -u user -p pass -gc dc.domain.local -c all

Domain Environment Mapping

• Domain Enumeration - Comprehensive AD reconnaissance

• BloodHound Analysis - Privilege escalation path identification

• Service Enumeration - SQL, Exchange, file servers, etc.

• Recent AD Vulnerabilities - crackmapexec smb range -M zerologon

Advanced Attack Techniques

• Delegation Attacks - Constrained/Unconstrained delegation abuse

• Certificate Attacks - AD CS vulnerabilities (if present)

• Backup System Targeting - Often contain high-privilege credentials

• Application-Specific Attacks - SQL injection, web app vulnerabilities

Phase 4: Lateral Movement & Persistence (30 minutes)

# ✅ Systematic Lateral Movement
crackmapexec smb target_range -u admin -H hash --pwn3d

Lateral Movement Techniques

• Pass-the-Hash - psexec.py -hashes :hash admin@target

• Pass-the-Ticket - kerberos::ptt ticket.kirbi

• Golden/Silver Tickets - kerberos::golden for persistence

• WMI/WinRM - Alternative execution methods

Persistence & Impact

• Backdoor Accounts - Create domain admin accounts for persistence

• Data Extraction - Identify and document sensitive data access

• Service Disruption Testing - Demonstrate impact potential

• Complete Domain Compromise - NTDS.dit extraction if possible

Phase 5: Post-Domain Compromise - "Welcome to My Domain!" 🦝 (60 minutes)

# ✅ Maximum Value Demonstration
secretsdump.py domain/[e-mail] -ntds

Post-Domain Compromise Strategy - Complete Value Demonstration

• NTDS.dit Extraction - secretsdump.py domain/admin@dc -just-dc-ntlm

• Password Cracking Analysis - hashcat -m 1000 ntds_hashes.txt rockyou.txt

• Golden Ticket Creation - mimikatz "kerberos::golden /krbtgt:HASH"

• Sensitive Data Discovery - Enumerate shares for confidential information

• Persistence Establishment - Golden tickets and backdoor accounts

• Business Impact Documentation - Quantify the compromise impact

• Attack Chain Validation - Test alternative compromise methods

• Professional Cleanup - Document and remove all persistence mechanisms

🎯 PJPT Success Strategy

Time Management (4-6 hours total)

1. Hour 1: Network discovery and initial access attempts

2. Hour 2: Post-compromise quick wins and immediate credential gathering

3. Hour 3-4: Deep enumeration and privilege escalation

4. Hour 5-6: Lateral movement, persistence, and documentation

Documentation Priorities

1. Clear Attack Chain - Document step-by-step progression from initial access to domain admin

2. Command Evidence - Include exact commands used and their outputs

3. Impact Assessment - Demonstrate business impact of compromise

4. Remediation Recommendations - Provide specific mitigation strategies

5. Timeline - Show progression and persistence of access

Common Pitfalls to Avoid

• Don't Skip Quick Wins - Always try Kerberoasting and GPP attacks first

• Don't Forget Token Impersonation - Check for high-value tokens after gaining admin access

• Don't Overlook Legacy Systems - Older systems often have exploitable vulnerabilities

• Don't Rush Documentation - Take screenshots and notes throughout the process

• Don't Ignore Lateral Movement - Demonstrate access to multiple systems

🔗 Integration Points

Attack Chain Combinations

• LLMNR Poisoning → Pass-the-Hash → Token Impersonation → Domain Admin

• Password Spraying → Kerberoasting → Lateral Movement → Mimikatz → Golden Ticket

• LNK File Attack → Credential Capture → GPP Enumeration → Service Account Compromise

Tool Integration Workflow

1. Responder captures initial credentials

2. CrackMapExec tests credential validity and finds admin access

3. Impacket tools perform targeted attacks (secretsdump, GetUserSPNs)

4. Metasploit provides automated enumeration (GPP, SMB enumeration)

5. Mimikatz extracts additional credentials from memory

6. BloodHound maps privilege escalation paths

7. Manual techniques fill gaps where automated tools fail

📝 Final Notes

This checklist represents a systematic approach to Active Directory penetration testing aligned with PJPT examination requirements. Each technique builds upon the previous ones, creating a comprehensive attack methodology.

Remember: The goal is not just to achieve domain admin access, but to demonstrate a thorough understanding of the attack chain, document findings professionally, and provide actionable remediation advice.

Practice Environment: Test all techniques in a lab environment before the exam. Tools and commands may behave differently across various Windows versions and domain configurations.

Time Management: Stick to the time allocations suggested above. It's better to have partial access with good documentation than complete access with poor documentation.

Good luck with your PJPT examination! 🚀
