Mastering Metasploit - Fourth Edition

By: Nipun Jaswal

Overview of this book

Updated for the latest version of Metasploit, this book will prepare you to face everyday cyberattacks by simulating real-world scenarios. Complete with step-by-step explanations of essential concepts and practical examples, Mastering Metasploit will help you gain insights into programming Metasploit modules and carrying out exploitation, as well as building and porting various kinds of exploits in Metasploit. Giving you the ability to perform tests on different services, including databases, IoT, and mobile, this Metasploit book will help you get to grips with real-world, sophisticated scenarios where performing penetration tests is a challenge. You'll then learn a variety of methods and techniques to evade security controls deployed at a target's endpoint. As you advance, you’ll script automated attacks using CORTANA and Armitage to aid penetration testing by developing virtual bots and discover how you can add custom functionalities in Armitage. Following real-world case studies, this book will take you on a journey through client-side attacks using Metasploit and various scripts built on the Metasploit 5.0 framework. By the end of the book, you’ll have developed the skills you need to work confidently with efficient exploitation techniques

Post-exploitation with RailGun

RailGun sounds like a top-notch gun spitting out bullets faster than light; however, this is not the case. RailGun allows you to make calls to a Windows API without the need to compile your own DLL. It supports various Windows DLL files and eases the way for us to perform system-level tasks on the victim machine. Let's see how we can perform various tasks using RailGun, and carry out some advanced post-exploitation with it.

Manipulating Meterpreter through Interactive Ruby Shell

RailGun requires the irb shell to be loaded into Meterpreter. Let's look at how we can jump to the irb shell from Meterpreter:

Figure 2.26 – Running the irb shell from Meterpreter

We can see in the preceding screenshot that merely typing in irb from Meterpreter allows us to drop in the Ruby-interactive shell. We can perform a variety of tasks with the Ruby shell from here. Metasploit also informs us that the client variable...
