What is Gobuster? How to Use It and Find Hidden Directories?

This is a very powerful and useful tool that is written in Go language, an open-source, low-level language (much like C or Rust) developed by a team at Google and other contributors.It is a helpful tool for security professionals to find hidden weaknesses in websites. By using it responsibly, we can help keep websites safe and secure.

The primary function of Gobuster is to discover hidden directories, files, and DNS subdomains on web servers. It does this by using a technique called “brute-forcing,” where it rapidly tests a list of potential paths (directories and files) against the target server. If a path exists, the server will return a positive response, which Gobuster then reports to the user.

Gobuster offers several modes of operation, each tailored to a specific type of enumeration:

  • Directory/File Enumeration: Scans for directories and files on a web server.
  • DNS Subdomain Enumeration: Identifies subdomains by testing a list of potential names.
  • Virtual Host Enumeration: Discovers virtual hostnames on a server.
  • Amazon S3 Bucket Enumeration: Finds open Amazon S3 buckets.
  • Google Cloud Bucket Enumeration: Locates open Google Cloud buckets.
  • TFTP Server Enumeration: Enumerates TFTP servers.

It’s a command-line tool, making it flexible and easily scriptable for automated tasks. Gobuster’s effectiveness and speed make it a popular choice among professionals for uncovering potential vulnerabilities that could be exploited by malicious actors
