Overview of this book

Nmap is a well known security tool used by penetration testers and system administrators. The Nmap Scripting Engine (NSE) has added the possibility to perform additional tasks using the collected host information. Tasks like advanced fingerprinting and service discovery, information gathering, and detection of security vulnerabilities."Nmap 6: Network exploration and security auditing cookbook" will help you master Nmap and its scripting engine. You will learn how to use this tool to do a wide variety of practical tasks for pentesting and network monitoring. Finally, after harvesting the power of NSE, you will also learn how to write your own NSE scripts."Nmap 6: Network exploration and security auditing cookbook" is a book full of practical knowledge for every security consultant, administrator or enthusiast looking to master Nmap.

Writing a brute force script


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 their 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 by using the NSE libraries brute, unpwdb, and creds to perform brute force password auditing against Wordpress installations.

How to do it...

Let's write an NSE script to brute force Wordpress accounts:

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

    description = [[
    performs brute force password auditing against Wordpress CMS/blog installations.
    
    This script uses the unpwdb and brute libraries to perform password guessing. Any successful guesses...
