Learning Python Web Penetration Testing: Automate web penetration testing activities using Python

Web application security testing becomes much more adaptable when you understand the tools behind it. In Learning Python Web Penetration Testing, Christian Martorella takes readers from the basics of an authorized testing workflow to building Python scripts for practical web-security tasks. The emphasis is hands-on: learn how requests, crawlers, discovery tools, and proxies work, then see how code can automate parts of the process.

Start with the shape of a web application

The book opens with penetration-testing methodology, common testing tools, and a lab environment. It then explains HTTP requests and responses before showing how to interact with web applications programmatically using Python’s Requests library. That groundwork helps connect protocol details to the behavior a tester actually observes.

Turn mapping and discovery into code

With Scrapy, readers build a crawler to map an application and follow links recursively. The next chapters explore resource discovery, including scripting tools to identify files and directories. Rather than treating these tasks as opaque scanner output, the material focuses on how a custom tool can gather and analyze results.

Examine authentication and injection risks

Further chapters cover password testing across basic, digest, and form-based authentication, followed by techniques for detecting and exploring SQL injection vulnerabilities. The final section introduces mitmproxy and shows how HTTP requests can be intercepted, manipulated, and used in automated testing workflows.

A practical starting point for Python-minded developers

Basic Python or scripting experience is expected, but advanced Python expertise is not. Web developers stepping into application security will find a clear route through core concepts and guided tool-building exercises. Use the techniques only in a lab or on systems for which you have explicit authorization.
