Python Ethical Hacking from Scratch

By: Fahad Ali Sarwar

Overview of this book

Penetration testing enables you to evaluate the security or strength of a computer system, network, or web application that an attacker can exploit. With this book, you'll understand why Python is one of the fastest-growing programming languages for penetration testing. You'll find out how to harness the power of Python and pentesting to enhance your system security. Developers working with Python will be able to put their knowledge and experience to work with this practical guide. Complete with step-by-step explanations of essential concepts and practical examples, this book takes a hands-on approach to help you build your own pentesting tools for testing the security level of systems and networks. You'll learn how to develop your own ethical hacking tools using Python and explore hacking techniques to exploit vulnerabilities in networks and systems. Finally, you'll be able to get remote access to target systems and networks using the tools you develop and modify as per your own requirements. By the end of this ethical hacking book, you'll have developed the skills needed for building cybersecurity tools and learned how to secure your systems by thinking like a hacker.

Decrypting the network traffic

As we saw in the previous section, we can intercept traffic using a man in the middle attack. However, this attack is rarely useful on its own since all the browser traffic nowadays is encrypted, so even if you were able to intercept traffic, you won't be able to do much. You can bypass this procedure by using SSL stripping. Intercepting traffic without encryption is also sometimes useful when you want to monitor a user's activity. This can help you figure out which websites a user is visiting the most. Using this information alongside social engineering attacks can help you compromise the victim's machine.

HTTPS versus HTTP

To understand how SSL stripping works, we need to understand how the hypertext transfer protocol (HTTP) and HTTPS protocols work. HTTPS is a secure version of HTTP, as indicated by the S at the end of its name. It was developed in the early days of the internet, when information was sent in the form of human...
