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 an attack using DNS redirection

If an attacker or penetration tester has compromised a host on the internal network, they can escalate the attack using DNS redirection. This is generally considered to be a horizontal attack (it compromises persons of roughly the same access privileges); however, it can also escalate vertically if the credentials from privileged persons are captured. In this example, we will use BetterCap, which acts as a sniffer, interceptor, and logger for switched LANs. It facilitates man-in-the-middle attacks, but we will use it to launch a DNS-redirection attack to divert users to sites used for our social engineering attacks.

To start the attack, the following options are available in the new version of BetterCap:

We should be able to activate any module that is required; for example, we will now try the DNS spoof attack module on the target by creating a file called dns.conf with the IP and domain details shown in the following screenshot. This will enable...
