Hands-On Penetration Testing with Kali NetHunter

By: Glen D. Singh, Sean-Philip Oriyano

Overview of this book

Kali NetHunter is a version of the popular and powerful Kali Linux pentesting platform, designed to be installed on mobile devices. Hands-On Penetration Testing with Kali NetHunter will teach you the components of NetHunter and how to install the software. You’ll also learn about the different tools included and how to optimize and use a package, obtain desired results, perform tests, and make your environment more secure. Starting with an introduction to Kali NetHunter, you will delve into different phases of the pentesting process. This book will show you how to build your penetration testing environment and set up your lab. You will gain insight into gathering intellectual data, exploiting vulnerable areas, and gaining control over target systems. As you progress through the book, you will explore the NetHunter tools available for exploiting wired and wireless devices. You will work through new ways to deploy existing tools designed to reduce the chances of detection. In the concluding chapters, you will discover tips and best practices for integrating security hardening into your Android ecosystem. By the end of this book, you will have learned to successfully use a mobile penetration testing device based on Kali NetHunter and Android to accomplish the same tasks you would traditionally, but in a smaller and more mobile form factor.

The need for sniffing traffic


Why does a penetration tester need to understand the benefits of packet sniffing? Packet sniffing enables a penetration tester to monitor and capture network traffic along a segment of the network. Sniffing on a computer network is also a form of wiretapping. Wiretapping involves implanting a device into traffic along a wire, such as a network cable or a telephone wire, for the purpose of monitoring and capturing sensitive data.

The following are some examples of sensitive information that may be captured by a packet sniffer:

  • Telnet traffic
  • FTP usernames and passwords
  • DNS traffic
  • Web traffic
  • Email traffic
  • Generally any username and password sent in plaintext format

These are just a few, however a lot more information is sent along the network in the form of bits. A sniffer can be either hardware-based or software-based to be planted on a network. A hardware-based sniffer usually has at least two interfaces (ports); this allows the hardware-based sniffer to be placed...
