There are many organizations out there that are looking for penetration testers, hackers and consultants to help them find vulnerabilities in their code before the bad guys do to ensure the security and integrity of their systems and information. As such, companies are willing to pay a premium for these services to protect their reputation and this makes ethical hacking a highly lucrative profession.
Not only is it possible to work for these organizations as a full-time pentester, it is also possible to make money through the various bug bounty programs that are on offer, such as Bug Crowd and HackerOne.
So that's they 'why' covered, so how do you actually become an ethical hacker?
Well there are many ways to learn ethical hacking. You can learn to hack through online hacking tutorials, watch YouTube videos on hacking, learn by hacking deliberately vulnerable websites or you can start to learn by reading books about hacking and giving it a go yourself.
20 Best Hacking Books
So which books should you read then? Well admittedly there's a lot of hacking books out there, some good, some not so good. So what I've done is select the twenty best hacking books based on popularity and the general consensus on some of the hacking subreddits.
This list is the best of the best if you like, but they're not in any specific order. I do however have a favourite that I will reveal at the end ;)
So without further ado, here they are:

Black Hat Python: Python Programming for Hackers and Pentesters
When it comes to hacking, hackers often turn to popular hacking tools such as Burp Suite to find their vunlerabilities. Despite these tools, hackers also create their own powerful and effective hacking tools on the fly and often, Python is the language of choice because it's easy to use, versatile and you build proof of concepts in minutes with relatively few lines of code.
In Black Hat Python, the latest book from Justin Seitz (and author of the best-selling Gray Hat Python), you'll explore the darker side of Python's capabilities. It will teach you how to write network sniffers, manipulate packets, infect virtual machines, create stealthy trojans, and much more.
Other things this book covers are how to create a trojan command-and-control using GitHub, how to detect sandboxing and automate common malware tasks, like keylogging and screenshotting and how to escalate Windows privileges with creative process control.
One of the best things about this book is that it teaches you how to extend the popular Burp Suite web-hacking tool so you can create your own custom plugins and extensions to help you find potentially lucrative and critical vulnerabilities faster.
Network Security Assessment 2nd Edition
Let's face it, the best form of defence is attack, so if you want to secure your network or find out how secure it really is, then probably the best way to find out is to attack it.
Network Security Assessment provides you with the tricks and tools you need to use as an ethical hacker to identify and assess risks in internet-based networks. Outlined in this book is the same penetration testing model used to secure government, military, and commercial networks. And with this book, you can adopt, refine, and reuse this testing model to design and deploy your own networks that are hardened and immune from attack.
This book demonstrates how a determined attacker browses around Internet-based networks to find vulnerable components, not only at the network level but also at the application level too. This latest edition contains all the latest hacking techniques, but also teaches you how to create defensive strategies against entire attack categories which will help you secure your networks both in the short term and the long term.
When it comes to offensive computing concepts, Violent Python takes you from theory right through to a practical implementation. Rather than relying on another attacker's tools, this book will teach build your own attack weapons using the Python programming language. This book demonstrates how to write Python scripts to automate large-scale network attacks, extract metadata, and investigate forensic artifacts.
It also shows you how to write code to intercept and analyze network traffic using Python, craft and spoof wireless frames to attack wireless and Bluetooth devices, and also how to data-mine popular social media websites. It even shows you how to evade modern anti-virus.
By reading this book you will gain a better understanding of IT security as a whole and also a good understanding of the Python language. Violent Python is really aimed at beginners and so more advanced readers may not find the book as useful.
Metasploit: The Penetration Tester's Guide
The Metasploit Framework is a well known tool for quickly discovering, exploiting, and sharing vulnerabilities and is used by security professionals everywhere.
