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.

Listing MySQL databases

MySQL servers support storing multiple databases per instance. As system administrators with legitimate access or penetration testers who just compromised the server, we can list the available databases using Nmap. This is especially useful when we don't have a MySQL client at our disposal to quickly check what kind of information is stored in the database.

This recipe teaches how to use Nmap NSE to list databases in a MySQL server.

How to do it...

Open a terminal and enter the following command:

$ nmap -p3306 --script mysql-databases --script-args mysqluser=   <user>,mysqlpass=<password> <target>

The databases should be listed under the script results:

   3306/tcp open  mysql 
   | mysql-databases:   
   |   information_schema 
   |   temp 
   |   websec 
   |   ids 
   |_  crm

How it works...

The argument -p3306 --script mysql-databases --script-args mysqluser=<user>,mysqlpass=<password> tells Nmap to attempt a connection to the MySQL server...
