Gain a reality check on XSS hacking techniques. Learn there is no magic hack and apply context, planning, and deep internet knowledge, including JavaScript and web architectures, to adapt techniques.
Learn how dom based xss attacks exploit client-side scripts by reading and writing to the dom with unsafe data from urls, bypassing server-side protections and logs.
Apply xss protection by escaping user input with htmlspecialchars in PHP to prevent dangerous characters from being interpreted in HTML, demonstrating input validation and safer rendering of untrusted data.
Explore how JavaScript can be triggered across diverse HTML elements, showcasing XSS techniques with image, SVG, object, input, and audio tags and event handlers like onfocus and onclick.
Demonstrate xss cross-site scripting tactics to steal credentials with a jquery-powered pop-up login prompt, and explain escaping input with htmlspecialchars to prevent such attacks.
Discover how cross-site scripting enables keylogging by capturing keystrokes on a vulnerable page and sending data to a server, with defenses using the htmlspecialchars function to prevent it.

Demonstrates dom based xss in google's xss game level 3 by editing url hash to inject payloads into image tags, escaping quotes, and triggering an alert to complete level 3.
Explore XSS cross-site scripting attack techniques by triggering an alert through an input field and onload scripts, examining how payloads appear in page elements and HTML attributes.
Cross Site Scripting or XSS is a hacking technique that exists for few decades now and that keeps on developing.
It is considered to be the most common vulnerability that has been in the OWASP top 10 for years.
Only here on Udemy!
You will learn how to test web application for Cross Site Scripting manually by preforming code injection from the start, as well as performing various XSS attacks through different XSS examples (changing content, session hijacking, etc) by using various XSS payloads at the same time.
We will go through basic types of Cross Site Scripting such as Stored XSS, Reflected XSS, Dom-Based XSS and we'll explain how you can pass through all of the XSS challenges from one of the biggest Internet companies of today.
After this course you should be able to without any problems comprehend how to fix Cross Site Scripting vulnerabilities by using input validation and output escaping everywhere on the web application where it's necessary.
Even though I believe that general Hacking Tutorials that cover different topics are quite good to understand what is Ethical Hacking in general and what cyber security jobs are all about, putting "Hacking for beginners" in your resume is not really an option. But if you pass this hacking course with attention and get a good understanding of what is Cross Site Scripting, you'll have a valuable cyber security skill under your belt that will look good in every resume of the future pen-tester, cyber security consultant, and even a web developer.
In this course my intention is not only to pass you the knowledge about XSS, but to direct you to adopt a certain mindset that will lead you to results.
Since you’ve decided for this subject, I guess you have a solid knowledge of Internet Technologies, HTML, JavaScript and some server side programming language.
