TryHackMe: The Last Trial Walkthrough and Review
The Last Trial is a challenging and informative TryHackMe box that requires a comprehensive understanding of various penetration testing techniques. In this review, we'll walk through the box, discuss the key steps and challenges, and provide insights into the learning experience.
Box Overview
The Last Trial is a moderately difficult box that simulates a real-world penetration testing scenario. The box focuses on exploiting vulnerabilities in a Windows-based system, with a emphasis on privilege escalation and lateral movement.
Initial Reconnaissance
The journey begins with a standard nmap scan, which reveals several open ports, including SMB (445), WinRM (5985), and HTTP (80). The scan results provide a good starting point for further exploration.
Initial Exploitation
The first challenge lies in exploiting the SMB service. After analyzing the SMB shares, you discover a shared folder called " trials" containing a hint and a password-encrypted zip file. The password for the zip file is hidden in a cleverly disguised note within the shared folder.
Escalation and Lateral Movement
Once inside the zip file, you gain access to a password, which leads to a successful WinRM login. The WinRM session provides a foothold for further exploitation. By analyzing the system configuration and running processes, you identify a vulnerable service running with elevated privileges.
Privilege Escalation
The box requires you to exploit a vulnerable driver to gain elevated privileges. This involves understanding Windows kernel architecture, driver interactions, and the Windows API. A clever exploitation leads to a SYSTEM-level shell, demonstrating the power of combining low-level system knowledge with practical exploitation techniques.

The Last Trial is a challenging Windows-based room on TryHackMe that focuses on Active Directory (AD) exploitation and Privilege Escalation
. Completing this room and obtaining the "Verified" status requires a deep understanding of post-exploitation techniques. 🚩 Room Overview Difficulty: Medium/Hard Operating System: Focus Areas:
Enumeration, BloodHound analysis, GPO manipulation, and AD CS (Active Directory Certificate Services) exploitation. 🔑 Key Phases of the Attack Initial Access Start with thorough scans to find open ports (80, 135, 445, 88).
Enumerate web services to find hidden directories or login portals.
Look for leaked credentials or misconfigured services for a foothold. Internal Enumeration BloodHound (SharpHound.exe) to map out the domain.
Identify high-value targets like Domain Admins or users with sensitive permissions. Group Policy Objects (GPOs) that you can modify. Privilege Escalation & Lateral Movement GPO Abuse:
If you have write access to a GPO, you can push a scheduled task to gain a shell as SYSTEM. AD CS Exploitation:
Check for vulnerable Certificate Templates (e.g., ESC1 or ESC3) using tools like Credential Harvesting:
Use Mimikatz or check LSASS memory if you gain administrative access on a workstation. 💡 Pro-Tips for Success Tunneling:
You will likely need a stable tunnel (like Chisel or Socat) to route your tools from your attack box into the internal network.
AD environments are sensitive. Ensure you delete any temporary GPOs or scripts used during the process. Stay Persistent:
If a service seems unresponsive, try resetting the machine; the AD lab environment can sometimes be resource-heavy. ✅ Getting the "Verified" Badge To get the verified checkmark on TryHackMe for this room: Submit all flags:

Before we dissect the verification process, let's establish context. "The Last Trial" is not your average beginner-friendly room. It is typically categorized as an Advanced level challenge, often falling under the "Red Teaming" or "Penetration Testing" pathways.
The room simulates a real-world scenario where you must compromise a target machine using a combination of:
The name itself implies a final test—a culmination of everything you have learned on the platform. It is designed to be the "last trial" before you consider yourself job-ready.
Run winpeas.exe via proxychains. The verified vulnerability is a CVE-2021-36934 (HiveNightmare) because the room creator deliberately forgot to fix the SAM file permissions.
Dump SAM:
reg save hklm\sam sam.save
reg save hklm\system system.save
Download to attacker, use secretsdump.py to get Administrator hash. Pass-the-hash to gain SYSTEM.
Use strings and ltrace:
ltrace /usr/bin/verify_access
It calls access("/root/verified.flag", F_OK). If the file exists, it gives root shell. Since you can’t create /root/verified.flag without root, you need to exploit a TOCTOU (Time of Check, Time of Use) race condition.
