Overview of this book

This is the second edition of ‘Nmap 6: Network Exploration and Security Auditing Cookbook’. A book aimed for anyone who wants to master Nmap and its scripting engine through practical tasks for system administrators and penetration testers. Besides introducing the most powerful features of Nmap and related tools, common security auditing tasks for local and remote networks, web applications, databases, mail servers, Microsoft Windows machines and even ICS SCADA systems are explained step by step with exact commands and argument explanations. The book starts with the basic usage of Nmap and related tools like Ncat, Ncrack, Ndiff and Zenmap. The Nmap Scripting Engine is thoroughly covered through security checks used commonly in real-life scenarios applied for different types of systems. New chapters for Microsoft Windows and ICS SCADA systems were added and every recipe was revised. This edition reflects the latest updates and hottest additions to the Nmap project to date. The book will also introduce you to Lua programming and NSE script development allowing you to extend further the power of Nmap.

Finding root accounts with an empty password in MySQL servers

New system administrators and distracted users often make the mistake of leaving the root account of a MySQL server with no password. This is a blatant security vulnerability that could be exploited by attackers. Penetration testers and system administrators need to detect these vulnerable installations before the bad guys do.

This recipe will show you how to use Nmap to check for empty root passwords in MySQL servers.

How to do it...

Open a terminal and enter the following command:

$ nmap -p3306 --script mysql-empty-password <target>

If the accounts root or anonymous have an empty password, it will be shown in the script results:

   Nmap scan report for 127.0.0.1 
   Host is up (0.11s latency). 
   3306/tcp open  mysql 
   | mysql-empty-password: 
   |_  root account has empty password

How it works...

The argument -p3306 --script mysql-empty-password make Nmap launch the NSE script mysql-empty-password if a MySQL server is found...
