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.

DoS attack modules


In previous chapters, we learned to use Metasploit in a variety of attack scenarios. In this recipe, we will focus on Denial-of-Service (DoS) attacks. DoS attacks focus on making resources unavailable for the purpose for which they were designed. DoS modules help penetration testers in attack services figure out if clients are susceptible to such attacks. So let's discuss some of these modules in detail.

How to do it...

In this recipe, we will focus on two of the most commonly attacked protocols, HTTP and SMB.

HTTP

We will start by having a look at the MS15-034 HTTP Protocol Stack Request Handling Denial-of-Service auxiliary module. This module checks if hosts are vulnerable to CVE-2015-1635 (MS15-034), a vulnerability in the HTTP protocol stack (HTTP.sys) that could result in arbitrary code execution.

  1. To use the module, set the target IP address of the Metasploitable 3 target machine and run it:
msf > use auxiliary/dos/http/ms15_034_ulonglongadd
msf auxiliary(dos/http/ms15_034_ulonglongadd...
