Metasploit Penetration Testing Cookbook - Third Edition

By: Daniel Teixeira, Abhinav Singh, Nipun Jaswal, Monika Agarwal

Overview of this book

Metasploit is the world's leading penetration testing tool and helps security and IT professionals find, exploit, and validate vulnerabilities. Metasploit allows penetration testing automation, password auditing, web application scanning, social engineering, post exploitation, evidence collection, and reporting. Metasploit's integration with InsightVM (or Nexpose), Nessus, OpenVas, and other vulnerability scanners provides a validation solution that simplifies vulnerability prioritization and remediation reporting. Teams can collaborate in Metasploit and present their findings in consolidated reports. In this book, you will go through great recipes that will allow you to start using Metasploit effectively. With an ever increasing level of complexity, and covering everything from the fundamentals to more advanced features in Metasploit, this book is not just for beginners but also for professionals keen to master this awesome tool. You will begin by building your lab environment, setting up Metasploit, and learning how to perform intelligence gathering, threat modeling, vulnerability analysis, exploitation, and post exploitation—all inside Metasploit. You will learn how to create and customize payloads to evade anti-virus software and bypass an organization's defenses, exploit server vulnerabilities, attack client systems, compromise mobile phones, automate post exploitation, install backdoors, run keyloggers, highjack webcams, port public exploits to the framework, create your own modules, and much more.

Understanding Meterpreter networking commands


Meterpreter provides us with some useful networking commands as well. These commands can be useful in understanding the network structure of the target user. We can analyze whether the system belongs to a LAN or if it is a standalone system. We can also find out the IP range, DNS, and other information. Such network information can be useful when we have to perform pivoting. Pivoting is a concept by which we can compromise other machines on the same network in which our target is present. We will also understand pivoting, where we will focus on the advanced use of Meterpreter.

Getting ready

Before we get into the recipe, there are three networking terms that we will encounter here. So, let's give our memory a quick brush over by looking at the following terms:

  • Subnetwork or subnet is the concept of dividing a large network into smaller, identifiable parts. Subnetting is done to increase the address utility and security.
  • A netmask is a 32-bit mask...
