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.

The Cross-Site Scripting framework

Cross-Site Scripting (XSS) vulnerabilities are the most reportedly exploitable vulnerabilities found in websites. It is estimated that they are present in nature due to lack of input data sanitization.

An XSS attack involves three parties: an attacker, a victim, and a vulnerable website or web application. The attack hinges on the fact that the vulnerable website has a script that returns user input in an HTML page without first sanitizing that input. This allows the attacker to input JavaScript code, which is executed by the victim's browser. As a result, it is possible to form links to the vulnerable site where one of the parameters consists of malicious JavaScript code. The JavaScript code will be executed by the victim's browser in the vulnerable website's context, granting the attacker access to the victim's cookies for the vulnerable website.

There are at least two primary types of XSS vulnerabilities: nonpersistent and persistent.
