Featuring 15 code-based challenges with unlimited attempts, this hands-on test lets you sharpen your XSS exploitation skills using real tools. Use a built-in JavaScript editor to simulate attacks and reconnaissance techniques such as understanding what Cross-Site Scripting and sandboxing are, exfiltrating data with JavaScript APIs, exploiting various types of XSS, and learning how to exploit different types of data. Each task mirrors real-world exam scenarios, helping you prepare for certification by actively scripting and executing simulated client-side attacks.
