Application Security

Description: In this course, you will develop the skills you need to successfully perform and combat Cross-Site Scripting (XSS) attacks. XSS is one of the top 10 most dangerous and common web application attacks according to both OWASP and CWE. I've spent months creating and collecting the best resources on XSS to put them in this course so that you can learn Cross-Site Scripting in a fun, efficient, and practical manner.

In order to truly understand how XSS works and how to defend against it, you have to learn hands-on by executing attacks against vulnerable applications and then looking at secure versions of the same code, and that's exactly what you'll do in this course. We start out by explaining the concepts of XSS and its 3 main types: Reflected, Stored (Persistent), and DOM-based. Then, we take a look at case studies of recent real-world XSS vulnerabilities in Facebook, Gmail, Twitter, Tesla, Airbnb, and TikTok. After that, we spin up a lab environment to perform all 3 types of attacks with both manual and automated approaches. We then set up, configure, and use a powerful browser exploitation framework called BeEF to deliver a payload that hooks unsuspecting browsers. From there, you can launch a number of different attacks using BeEF command modules (ie: scanning internal networks, defacing websites, compromising routers, and more). Next, we apply everything we've learned to pentest the OWASP Juice Shop starting with information gathering, and then exploiting all 3 types of XSS. Finally, we wrap up the course by discussing the most (and least) effective defensive controls, including rules, cheat sheets, and recommended code review techniques to properly defend your applications from this dangerous threat.

If you're looking for a hands-on way to learn Cross-Site Scripting, this is your course!

Description: Learn how to use sqlmap in-depth for professional engagements like pentests or bug bounties. sqlmap is the most powerful and widely used SQL injection tool, and for good reason. It packs an impressive array of features and options specifically crafted to fingerprint, enumerate, and takeover databases as well as underlying systems. In this course, we take a look at all of that. We start by looking at the sqlmap project, including how the source code repository is structured, where to find important files such as configuration and payload files, and how to set up a home lab environment to safely and legally practice what we're learning. Then, we explore every single option that sqlmap offers with examples and explanations of how and when to use the option(s). We learn tips & tricks to see what sqlmap is doing under the hood and to troubleshoot when we come across issues. Once we've covered sqlmap's options and features, we tie it all together by running through scenarios. This is when we get to see how those options can be used together or on their own to achieve our pentest or bug bounty objectives. The course also includes sections dedicated to specific topics such as bypassing WAFs and evading security controls, and how to run sqlmap as an API.
