Once you identify an interesting directory (let's assume /admin ), you might find that accessing it directly yields a 403 Forbidden or simply a blank page. You need to find specific files inside that directory.
Another versatile tool designed for web application testing, excellent for finding hidden parameters.
In the realm of web security, "Fuzzing" is the art of the unknown. It’s the process of sending unexpected, malformed, or semi-random data to an application to see what breaks, what leaks, and what’s hidden. When you face the , you aren't just looking for files; you are mapping the invisible attack surface of a target.
Web servers often return generic responses (like customized 404 pages or 200 OK statuses filled with error text) that mask your actual results. You must use filters to eliminate false positives: -fc : Filter by HTTP status (e.g., -fc 404,403 ). -fs : Filter by response size in bytes (e.g., -fs 1423 ). -fl : Filter by response lines (e.g., -fl 25 ). -fw : Filter by response words (e.g., -fw 312 ).

At user_id=1337 , the response changes: "role": "admin", "token": "eyJhbG..." . You have now passed the assessment's core objective. Once you identify an interesting directory (let's assume
Your first step on the target IP and port is to discover the directory structure. While tools like gobuster or feroxbuster provide incredible speed for recursive fuzzing, offers the granular control needed to filter out false positives. Directory Fuzzing Command with ffuf

Make sure to replace <TARGET_IP> with the actual IP address of the target. Also note that you must have the base domain ( academy.htb ) in your /etc/hosts file pointing to the target IP for this to work correctly.
