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.

Bypassing the MAC address authentication and open authentication


The Media Access Control (MAC) address uniquely identifies each node in a network. It takes the form of six pairs of hexadecimal digits (0 to 9 and the letters A to F) that are separated by colons or dashes, and usually appears like this: 00:50:56:C0:00:01.

The MAC address is usually associated with a network adapter or a device with networking capability; for this reason, it's frequently called the physical address.

The first three pairs of digits in the MAC address are called the Organizational Unique Identifier, and they serve to identify the company that manufactured or sold the device. The last three pairs of digits are specific to the device and can be considered to be a serial number.

Because a MAC address is unique, it can be used to associate a user to a particular network, especially a wireless network. This has two significant implications—it can be used to identify a hacker or a legitimate network tester who has tried...
