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.

Large-scale scanning

In case of testing bigger organizations with multiple class B/C IP ranges, large-scale scanning is engaged. For example, with a global company, often a number of IP blocks exist as part of external internet facing. As mentioned earlier in Chapter 2, Open Source Intelligence and Passive Reconnaissance, attackers do not have time limitations to scan, but penetration testers do. Pentesters can engage multiple tools to perform the activity; Masscan is one of the tools that would be engaged to scan large-scale IP blocks to quickly analyze the live hosts in the target network. Masscan is installed in Kali by default. The biggest advantage of Masscan is randomization of hosts, ports, speed, flexibility, and compatibility. The following screenshot provides a Class C scanning network within a few seconds to complete and identify the available HTTP service on port 80 and services running on the target hosts:
