Mastering Kali Linux for Advanced Penetration Testing - Third Edition

By: Vijay Kumar Velu, Robert Beggs

Overview of this book

This book takes you, as a tester or security practitioner, through the reconnaissance, vulnerability assessment, exploitation, privilege escalation, and post-exploitation activities used by pentesters. To start with, you'll use a laboratory environment to validate tools and techniques, along with an application that supports a collaborative approach for pentesting. You'll then progress to passive reconnaissance with open source intelligence and active reconnaissance of the external and internal infrastructure. You'll also focus on how to select, use, customize, and interpret the results from different vulnerability scanners, followed by examining specific routes to the target, which include bypassing physical security and the exfiltration of data using a variety of techniques. You'll discover concepts such as social engineering, attacking wireless networks, web services, and embedded devices. Once you are confident with these topics, you'll learn the practical aspects of attacking user client systems by backdooring with fileless techniques, followed by focusing on the most vulnerable part of the network – directly attacking the end user. By the end of this book, you'll have explored approaches for carrying out advanced pentesting in tightly secured environments, understood pentesting and hacking techniques employed on embedded peripheral devices.

Escalating access rights in Active Directory


We have just explored how to escalate privileges within a system and how to grab credentials over the network. Now let's utilize all the details that we have collected so far; 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 situational_awareness module, get_domain_controller:

usemodule situational_awareness/network/powerview/get_domain_controller

To identify who is logged into the domain, attackers can utilize the get_loggedon module, described as follows:

usemodule situational_awareness/network/powerview/get_loggedOnexecute

All users who logged into the domain...
