Metasploit Penetration Testing Cookbook

By: Abhinav Singh

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.

Passing the hash


Passing the hash or hashdump is the process of extracting the Windows logon hash files. Hashdump meterpreter script extracts and dumps the password hashes from the target machine. Hashes can be used to crack the logon passwords and gain authorized entry into other systems on the LAN for future pen tests.

Getting ready

Before starting with the recipe, let us first understand about Windows passwords and their storage format.

When you type your password into the Windows Logon screen, it encrypts your password using an encryption scheme that turns your password into something that looks like this:

7524248b4d2c9a9eadd3b435c51404ee

This is a password hash. This is what is actually being checked against when you type your password in. It encrypts what you typed and bounces it against what is stored in the registry and/or SAM file.

The SAM file holds the usernames and password hashes for every account on the local machine, or domain if it is a domain controller. It can be found on the...
