Servers often host multiple sites on one IP using Virtual Hosts. The assessment frequently requires discovering these by fuzzing the Host header.

The assessment tests your ability to use ffuf (Fuzz Faster U Fool) to map an application's hidden attack surface. Success relies on choosing the correct wordlists—typically from SecLists —and applying filters to remove "noise" like common 403 or 404 responses. 2. Core Methodology & Techniques Directory and File Discovery htb skills assessment - web fuzzing
Begin by identifying the base structure of the web server. Unlike standard reconnaissance, you must often use to find nested directories like /admin/ and then fuzz within those for specific file types.
ffuf -w subdomains.txt -u http:// : / -H 'Host: FUZZ.academy.htb' -fs Servers often host multiple sites on one IP
If you hit a 403 Forbidden on a directory, don't stop. Fuzz for extensions (e.g., .php , .php7 , .html ) within that directory to find accessible pages like panel.php . Virtual Host (VHost) Fuzzing
Once a VHost like admin.academy.htb is found, you must add it to your /etc/hosts file to interact with it through a browser or further tools. Parameter Fuzzing (GET and POST) Unlike standard reconnaissance, you must often use to
Once you find a hidden page, it may require specific parameters to function. You will use ffuf to discover both parameter names and their valid values.
