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.

IDS/IPS identification

Penetration testers can utilize fragroute and wafw00f to identify whether there are any detection or prevention mechanisms put in place such as Intrusion Detection System (IDS) or an Intrusion Prevention system (IPS) or a Web application Firewall (WAF).

fragroute is a default tool in Kali Linux that can perform fragmentation of packets. The network packets will allow attackers to intercept, modify, and rewrite the egress traffic for a specific target. This tool comes in very handy on a highly secured remote environment.

The following screenshot provides the list of options that are available in fragroute to determine any network IDs in place:

Attackers can also write their own custom configuration to perform fragmentation attacks to delay, duplicate, drop, fragment, overlap, reorder, source-route, and segment. A sample custom configuration would look like the following screenshot:

fragroute on target is as simple as running fragroute and if there are any connections...
