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

By: Vijay Kumar Velu

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

Summary

In this chapter, we looked at the methodology of escalating privileges and explored different methods and tools that can be utilized to achieve the goal of the penetration test.

We first started with common system-level privilege escalation using bypassuac, and also by utilizing existing Windows-scheduled tasks.

We focused on utilizing Meterpreter to gain system-level control and later we took a deep dive into PowerShell's Empire tool, followed by harvesting the credentials by using password sniffers on the network. We also utilized responder and SMB relay attacks to gain remote system access, and we used Responder to capture the passwords of different systems on a network that utilizes SMB.

We completely compromised an Active Directory using a structured approach. Finally, we exploited the access rights in an Active Directory using an Empire PowerShell, and compromised...
