Mastering Kali Linux for Advanced Penetration Testing, Second Edition - Second Edition

Overview of this book

This book will take you, as a tester or security practitioner through the journey of reconnaissance, vulnerability assessment, exploitation, and post-exploitation activities used by penetration testers and hackers. We will start off by using a laboratory environment to validate tools and techniques, and using an application that supports a collaborative approach to penetration testing. Further we will get acquainted with passive reconnaissance with open source intelligence and active reconnaissance of the external and internal networks. We will also focus on how to select, use, customize, and interpret the results from a variety of different vulnerability scanners. Specific routes to the target will also be examined, including bypassing physical security and exfiltration of data using different techniques. You will also get to grips with concepts such as social engineering, attacking wireless networks, exploitation of web applications and remote access connections. Later you will learn the practical aspects of attacking user client systems by backdooring executable files. You will focus on the most vulnerable part of the network—directly and bypassing the controls, attacking the end user and maintaining persistence access through social media. You will also explore approaches to carrying out advanced penetration testing in tightly secured environments, and the book's hands-on approach will help you understand everything you need to know during a Red teaming exercise or penetration testing

Large-scale scanning

When large companies require pen testing, large-scale scanning is used. For example, for 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. Pen testers can engage multiple tools to perform this activity; Masscan is one of the tools that could be used to scan large-scale IP blocks to quickly analyze the target's live hosts. Masscan is installed in Kali by default. The biggest advantage of Masscan is its randomization of hosts, speed, flexibility, and compatibility. The following screenshot provides a Class C scanning network within a few seconds to complete and identify the available ports and services running on the target hosts:
