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.

Installing backdoors


Having a shell on the target system is great, but sometimes it is not enough. With a backdoor, we will be able to ensure persistence and get access to the system, even if the vulnerability gets patched.

Getting ready

Now that we have a session in the target system, we will use that session to backdoor a service; in this recipe, we will start by backdooring the Apache server:

Next, we will use the Windows Registry Only Persistence local exploit module to create a backdoor that is executed during boot.

Lastly, we will use Windows Management Instrumentation (WMI) to create a persistent fileless backdoor. The WMI Event Subscription Persistence exploit module creates a permanent WMI event subscription to achieve file-less persistence.

How to do it...

  1. Since we cannot backdoor a binary while it is running, the first thing we need to do is to kill the Apache process (httpd.exe), using the kill command followed by the PID of the process:
meterpreter > kill 3820
Killing: 3820
