The first step in any penetration test is to enumerate the target machine to understand its attack surface.

The purpose of machines like is to highlight common security failures. hackfail.htb

With access to the disk group, you can effectively re-write the system's authentication logic. A typical attack sequence is:

Download and analyze the leaked source code. Code review is essential for finding logical flaws, hidden API endpoints, or hardcoded vulnerabilities. Analyzing the Web App

If you are looking to tackle a machine like , ensure your methodical approach to enumeration is robust, and don't be afraid to think outside the box when privilege escalation seems impossible. similar, more modern machines currently active on HTB

Navigating to http://hackfail.htb uncovers a custom-built web application. Automated directory fuzzing via tools like Gobuster or Feroxbuster helps map hidden login interfaces, API endpoints, or backup files. Identifying the Flaw

With a vulnerability identified, we can proceed with exploitation.

Purposely fail several SSH login attempts to trigger Fail2Ban. When Fail2Ban executes the modified action script to "ban" you, it executes your malicious command as the root user. 🛡️ Key Takeaways & Mitigation A typical attack sequence is: Download and analyze

: Searching for sensitive information in publicly accessible development files or environment variables. Web Vulnerabilities

Copy the recovered private key to your attacker machine, adjust its permissions, and connect:
