Overview

Fuzzer is a sophisticated security assessment tool designed to discover hidden or undocumented web resources. It employs an advanced, multi-threaded approach to systematically enumerate directories, files, and endpoints within web applications, helping security professionals map out the complete attack surface.

By leveraging intelligent wordlist processing and dynamic pattern matching, the fuzzer can reveal potential security vulnerabilities, sensitive information exposure, and unintended access points. The tool supports both managed and custom wordlists.

This fuzzer is capable of:

  • Fuzzing with several HTTP request methods (such as GET, POST, PUT, etc.)
  • Fuzzing for live hosts (subdomain bruteforcing)
  • Fuzzing for virtual hosts (VHOST enumeration)
  • Fuzzing for input parameters
  • Fuzzing with custom wordlists

​
Usage Examples

You can specify a target URL for Fuzzer to find hidden links, endpoints, files and application routes.
