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.

Wireless encryption standard


As a penetration tester, it's important to understand the various types of wireless encryption and their standards.

Wired Equivalent Privacy

The Wired Equivalent Privacy (WEP) standard was the first encryption standard implemented within an IEEE 802.11 network. It's designed to provide data confidentiality during all wireless communications between an access point and a client. WEP uses the RC4 encryption cipher/algorithm to ensure confidentiality during transmission; however, the WEP encryption standard uses a 24-bit initialization vector (IV). The IV, in this case, is used to create a stream of ciphers for the RC4 encryption algorithm.

The following are the various key sizes for WEP:

  • A 64-bit WEP uses a 40-bit key
  • A 128-bit WEP uses a 104-bit key
  • A 256-bit WEP uses 232-bit key

WEP has been known for its design flaws over the years and is considered a security vulnerability when applied to an IEEE 802.11 network.
