Description

With the huge growth in the number of web applications in the recent times, there has also been an upsurge in the need to make these applications secure. Web penetration testing is the use of tools and code to attack a website or web app in order to assess its vulnerabilities to external threats. While there are an increasing number of sophisticated ready-made tools to scan systems for vulnerabilities, the use of Python allows testers to write system-specific scripts, or alter and extend existing testing tools to find, exploit, and record as many security weaknesses as possible.

This course will walk you through the web application penetration testing methodology, showing you how to write your own tools with Python for every main activity in the process. It will show you how to test for security vulnerabilities in web applications just like security professionals and hackers do.

The course starts off by providing an overview of the web application penetration testing process and the tools used by professionals to perform these tests. Then we provide an introduction to HTTP and how to interact with web applications using Python and the Requests library. Then will follow the web application penetration testing methodology and cover each section with a supporting Python example. To finish off, we test these tools against a vulnerable web application created specifically for this course.

Stop just running automated tools—write your own and modify existing ones to cover your needs! This course will give you a flying start as a security professional by giving you the necessary skills to write custom tools for different scenarios and modify existing Python tools to suit your application’s needs.

Introduction
4 Lectures 26:22

This video provides an overview of the entire course.

Preview 05:58

You will learn about the web app penetration-testing methodology, the toolset, and our lab environment. 

Understanding Web Application Penetration Testing Process
07:50

You will learn about the traditional tools used by security professionals to perform penetration tests. This will provide a basic understanding of the most important type of tools used, and give us ideas on what we can build with Python. 

Typical Web Application Toolkit
06:19

We need to set up the testing environment and we would use VirtualBox, VM, text editor, and the vulnerable Web application we are going to use as target of our tests. 

Testing Environment
06:15
+
Interacting with Web Applications
4 Lectures 32:52

This video introduces HTTP, how it works, and the different methods available to communicate with an HTTP server. 

Preview 07:10

You’ll understand the anatomy of an HTTP request in order to make your own tools. 

Anatomy of an HTTP Request
07:56

We want to learn how to send HTTP request with Python. 

Interacting with Web Apps Using Requests Library
10:24

In this video, we are going to learn about HTTP response codes. 

Analyzing the Responses
07:22
+
Web Crawling with Scrapy
4 Lectures 20:36

You’ll learn about web application mapping, what it is, and how to do it. 

Preview 03:35

We want to create a web application crawler to help us map an application. 

Creating a Crawler with Scrapy
07:56

We created a basic crawler, but now, we want to make it recursive to cover all the web application content. 

Recursive Crawling
03:42

We need to extract information from the web application that will be useful for our Security testing. 

Extracting Information
05:23
+
Resources Discovery
5 Lectures 22:54

Most applications have resources that are not linked and tools such as crawlers or proxies won’t find. So, we need to discover resources with other methods. 

Preview 04:03

In order to find more resources that are not linked in a web application, we need to create a brute forcer in order to discover resources using dictionary files. 

Building Our First Brute Forcer
05:25

We need to improve the results of the brute forcer in order to facilitate the discovery of interesting resources. Let's do just this! 

Analyzing the Results
05:17

In this video, we will add the detection of redirections and generate more information about the responses, such as the time it takes the response and the MD5 hash of the content. 

Adding More Information
03:54

When conducting an analysis of big web applications, having a screenshot of the discovered resources could be very handy. We need to add this capability by taking a screenshot of all the resources that return a 200 status code. 

Taking Screenshots of the Findings
04:15
+
Password Testing
4 Lectures 21:27

The most important security control in a web application is the authentication. Let’s learn password testing and the different approaches. 

Preview 04:58

We want to create a brute forcer for Basic authentication in order to detect the valid passwords for a given user. 

Our First Password Brute Forcer
04:38

Some applications use an authentication method called Digest authentication, which is stronger and more secure than Basic authentication. We want to add support to this method to our script. 

Adding Support for Digest Authentication
04:43

You learned how to test Basic- and Digest-based authentication, but most of the web application use Form-based authentication, which is the famous login form. In this video, you will learn how we can brute force these forms. 

Form-based Authentication
07:08
+
Detecting and Exploiting SQL Injection Vulnerabilities
4 Lectures 22:55

SQL injection vulnerabilities are one of the most dangerous issues that can affect a Web application. In this section, you will learn what it is, how it works, and see the difference between SQLi and Blind SQLi. 

Preview 04:51

SQL injection is one of the most dangerous vulnerabilities in a web application. In this video, you will learn what the methods available for detecting it are, and then we will automate the process in Python. 

Detecting SQL Injection Issues
08:09

This video will focus on what an attacker can do after they find a valid SQLi. We will review the options and automate some of them in our script. 

Exploiting a SQL Injection to Extract Data
06:00

When exploiting SQLi, one the most important parts is to identify the names of the tables in the DB in order to find interesting data. Another important option is reading OS files as we can obtain more passwords and get the source code of the app to find other vulnerabilities. 

Advanced SQLi Exploiting
03:55
+
Intercepting HTTP Requests
5 Lectures 23:27

Being the proxy is one of the most useful tools in web app security testing. You will learn how it works, why they are used, and finally, the different types of HTTP proxies available. 

Preview 04:08

In this video, we will introduce mitmproxy and explain why it was chosen to learn about HTTP proxy in Python. 

Introduction to mitmproxy
03:53

The main functionality of an HTTP proxy is to intercept and manipulate traffic. In this video, we will note how to do this in mitmproxy. 

Manipulating HTTP Requests
06:53

In the previous video, we saw how mitmproxy works and how to manipulate the HTTP communication. Now, let’s take a look at how can we put together what we discussed before about SQLi in order to scan for SQLi issues while we browse. 

Automating SQLi in mitmproxy
04:38

In this video, we’ll look at wrapping up the course.
