Discover how session establishment works using PHP session files, the process of setting and storing session cookies in browsers, and how these cookies authenticate subsequent requests. Learn how malicious actors craft URLs to trick servers into performing unintended actions on behalf of authenticated users. Watch a live CSRF attack demonstration in a XAMPP environment, visualize session file creation on servers, and understand browser-based cookie storage. The video concludes with effective strategies and best practices to prevent CSRF attacks in web applications.
