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.

Chapter 13. Command and Control

Modern attackers are not interested in exploiting a system or network and then moving on; instead, the goal is to attack and compromise a network of value, and then remain resident on the network for as long as possible. Command and control (C2) refers to the mechanisms that testers use to replicate attacker actions by persisting on a system, maintaining two-way communications, enabling data to be exfiltrated to the tester's location, and hiding the evidence of the attack.

The final stage of the attacker's kill chain is the command, control, and communicate phase, where the attacker relies on a persistent connection with the compromised system to ensure that they can continue to maintain their control.

In this chapter, you will learn about the following topics:

  • Importance of persistence
  • Maintaining persistence with the Metasploit framework, PowerShell Empire, and online file sharing
  • Performing domain fronting techniques to maintain command and control
  • The art of...
