Mastering Kali Linux for Advanced Penetration Testing, Second Edition - Second Edition

Overview of this book

This book will take you, as a tester or security practitioner through the journey of reconnaissance, vulnerability assessment, exploitation, and post-exploitation activities used by penetration testers and hackers. We will start off by using a laboratory environment to validate tools and techniques, and using an application that supports a collaborative approach to penetration testing. Further we will get acquainted with passive reconnaissance with open source intelligence and active reconnaissance of the external and internal networks. We will also focus on how to select, use, customize, and interpret the results from a variety of different vulnerability scanners. Specific routes to the target will also be examined, including bypassing physical security and exfiltration of data using different techniques. You will also get to grips with concepts such as social engineering, attacking wireless networks, exploitation of web applications and remote access connections. Later you will learn the practical aspects of attacking user client systems by backdooring executable files. You will focus on the most vulnerable part of the network—directly and bypassing the controls, attacking the end user and maintaining persistence access through social media. You will also explore approaches to carrying out advanced penetration testing in tightly secured environments, and the book's hands-on approach will help you understand everything you need to know during a Red teaming exercise or penetration testing

Escalating access rights in Active Directory

We have just explored how to escalate privileges within a system, and how to grab the credentials over the network. Now let's utilize all the details that we have collected so far. And then we should be able to achieve the goal of penetration testing using the kill-chain methodology. In this section, we will escalate the privilege of a normal domain user to that of the domain administrator.

We identify the system that is connected to the domain and utilize our Empire PowerShell tool to escalate to the domain controller and dump all the username and password hashes:

You can harvest more information about the domain using the get_domain_controller situational awareness module:

Usemodule situational_awareness/network/powerview/get_group_member  

The second step is to invoke the wmi module from the Empire PowerShell tool. This will...
