Metasploit Penetration Testing Cookbook

Overview of this book

Metasploit® software helps security and IT professionals identify security issues, verify vulnerability mitigations, and manage expert-driven security assessments. Capabilities include smart exploitation, password auditing, web application scanning, and social engineering. Teams can collaborate in Metasploit and present their findings in consolidated reports. The goal of the software is to provide a clear understanding of the critical vulnerabilities in any environment and to manage those risks.Metasploit Penetration Testing Cookbook targets both professionals and beginners to the framework. The chapters of the book are logically arranged with an increasing level of complexity and cover Metasploit aspects ranging from pre-exploitation to the post-exploitation phase thoroughly. The recipe structure of the book provides a good mix of both theoretical understanding and practical implementation. This book will help readers in thinking from a hacker's perspective to dig out the flaws in target networks and also to leverage the powers of Metasploit to compromise them. It will take your penetration skills to the next level.The book starts with the basics such as gathering information about your target and gradually covers advanced topics like building your own framework scripts and modules. The book goes deep into operating systems-based penetration testing techniques and moves ahead with client-based exploitation methodologies. In the post- exploitation phase, it covers meterpreter, antivirus bypass, ruby wonders, exploit building, porting exploits to framework, and third party tools like armitage, and SET. Metasploit Penetration Testing Cookbook is the required guide to penetration testing and exploitation.

Railgun – converting Ruby into a weapon


In the previous recipe, we saw the use of the meterpreter API to run Ruby scripts. Let us take that a step ahead. Suppose we want to make remote API calls on the victim machine then what can be the simplest method? Railgun is the obvious answer. It is a meterpreter extension that allows an attacker to call DLL functions directly. Most often, it is used to make calls to the Windows API, but we can call any DLL on the victim's machine.

Getting ready

To start using Railgun, we will require an active meterpreter session on our target machine. To start the Ruby interpreter, we will use the irb command as discussed in the previous recipe.

How to do it...

Before we move into calling DLLs, let us first see the essential steps to follow in order to get the best out of Railgun.

  1. Identify the function(s) you wish to call.

  2. Locate the function on http://msdn.microsoft.com/en-us/library/aa383749(v=vs.85).aspx.

  3. Check the library (DLL) in which...
