Description

GooFuzz by m3n0sd0n4ld, is a tool written in Bash Scripting for fuzzing that uses an Open Source Intelligence (OSINT) approach to discover sensitive information on a target server. It uses advanced Google searches techniques (Google Dorking) and it can enumerate directories, files, subdomains, and parameters without leaving any evidence on the target’s server. This is useful for security professionals who want to identify vulnerabilities and weaknesses in their organization’s infrastructure before attackers do. It can be used to find hidden files and directories, enumerate subdomains, and discover sensitive information such as configuration files and login pages.

Download and install:

$ git clone https://github.com/m3n0sd0n4ld/GooFuzz.git

$ cd GooFuzz

$ chmod +x GooFuzz

$ ./GooFuzz -h

Example 1:

In this example we remove the subdomain “wiki.earthdata.nasa.gov” from the search.

Using the previous example, we create a file called “exclusion_list.txt” and insert the three subdomains to exclude, we perform the same search again, but passing the list of excluded targets.

Subdomains enumeration

The functionality to list subdomains (parameter “-s“) and in conjunction with a number of between 10 and 20 pages (parameter “-p“), it is possible to obtain a large number of subdomains of the organization.
