Web Hacking Language Review

In a lot of respects the rewards for web exploits are more immediately accessible than complex memory corruption exploits. Part of the reason is that web applications are designed to be more accessible than the musty insides of a kernel. The amount of knowledge you need to be efficient at web hacking and to really understand it can be daunting, especially if you don't come from a programming or systems engineering type background. We've observed a bit of a disparity in the skill sets of our students for Web Hacking, some come from a web application development background and the basics of the HTTP protocol are well known to them. Other students may not have a firm grasp on that subject matter so we're addressing that with the Web Hacking Language Review.The language review is a one day intensive designed to give you the basic fluency needed to be productive in the Web Hacking class itself.

The very first thing we do is a practical look at the HTTP protocol. You'll be interacting with simple web applications and viewing your traffic through various proxies and Wireshark to get a feeling for what's actually happening, we'll talk about useful information contained in the HTTP response headers and so forth.

Our next stop is Linux command line fundamentals. Many people are daunted by the power of the Linux CLI and try to stick with more GUI centered tools and operating systems. It's true that the Linux CLI is extremely powerful and therefore complex but understanding basic usage, file system layout and how to ask the OS for help will provide you with the confidence you need to start using Linux as your primary OS for penetration testing.

Python is the in house programming language at Immunity, all of our products rely on it and we write it every day. A key part of our educational philosophy is that you need to be able to implement an attack to really understand it. That means being able to write it up and for us (and you) that means Python. We'll be spending time giving you hands on experience setting up PIP the Python package manager and writing simple but effective scripts in Python.

JavaScript is everywhere and thanks to projects like Node.js is now doing everything. Having a firm understanding of JavaScript is essential for assessing Web 2.0 applications, Node.js applications and making your XSS do more than just shout alert('XSS!!!'); We'll be covering some of the language fundamentals and giving you some directed experience in writing JavaScript.

MySQL you can't really understand SQL Injection unless you understand SQL and MySQL is one of the most popular relational databases in use today. Virtually any PHP application will have a MySQL option for data store purposes and many applications depend on some type of SQL database (Microsoft SQL, PostgreSQL, Oracle, etc). During this class period we will provide you with a SQL database and help you extract data from it to understand what types of SQL queries you'll likely come into contact with in the wild.

This class review gives you the background you need to get the most out of our Web Hacking course. If you're not confident in any one of the above sections I would encourage you to come to the course and take the refresher because during the proper Web Hacking course we won't be covering these fundamentals.
