Writing brute force password auditing scripts


Brute force password auditing has become a major strength of the Nmap Scripting Engine. The library brute allows developers to quickly write scripts to perform custom brute force attacks. Nmap offers libraries such as unpwd, which give access to a flexible username and password database to further customize the attacks, and the library creds, which provides an interface to manage the valid credentials found.

This recipe will guide you through the process of writing your own brute force script with the NSE libraries brute, unpwdb, and creds to perform brute force password auditing against Wordpress installations.

How to do it...

  1. Create the file http-wordpress-brute.nse and fill the required information tags:

    CMS/blog installations. 

   This script uses the unpwdb and brute libraries to perform
