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.

ACK scans


Another interesting method of scanning is enabling the ACK flag within a packet. This technique is used to determine any form of filtering that may be performed by a network security device, such as a firewall.

While we haven't talked about firewalls yet, we are going to a little later. However, for right now, we will say that firewalls perform filtering of traffic from one network to another (for example, the internet to your local intranet

During a penetration test, we may be on the external network of the organization, such as the internet. Most organizations deploy a firewall at their perimeter, between the internet and their local area network (LAN) to help prevent any threats from entering or leaving their network. We can use an ACK scan to help us determine whether our target organization has a firewall in place. To execute an ACK scan, select ACK from the list in the nmap window in the NetHunter app and enter the target IP address:
