XSS: Reading Cookies from Vulnerable Websites

Understanding common web vulnerabilities is crucial for anyone involved in web development or cybersecurity. Cross-Site Scripting (XSS) remains a prevalent threat, often leading to data breaches and session hijacking. This course introduces you to the core concepts of XSS and its practical exploitation. By the end of this course, you will be able to identify, understand, and craft basic XSS payloads specifically designed to extract sensitive information like user session cookies from vulnerable web applications. This knowledge empowers you to better secure your own projects and critically assess the security posture of web applications. What you'll learn: * Understand the fundamental principles of Cross-Site Scripting (XSS) vulnerabilities. * Learn to identify different types of XSS, including reflected, stored, and DOM-based. * Craft effective XSS payloads to read and exfiltrate user session cookies. * Explore methods for bypassing basic Content Security Policies (CSP) against XSS. * Apply ethical hacking principles to test web applications for XSS weaknesses. * Practice implementing basic server-side and client-side defenses against XSS attacks. The course begins with a clear explanation of XSS concepts and its impact, then progresses to practical payload construction and testing. It concludes with discussions on modern mitigation strategies and best practices. This course is designed for absolute beginners interested in web security, ethical hacking, or web development, with no prior experience in cybersecurity required.
