Cross-site scripting (XSS) is a prevalent web security issue that can manifest in three types based on vulnerability impact: persistent, reflected, and self-XSS. Persistent XSS is the most severe, where attackers inject malicious scripts that permanently reside on a site, affecting all users who access the compromised page, as exemplified by the Samy worm on MySpace. Reflected XSS involves attackers crafting links that execute scripts from a website, often used for phishing by mimicking login pages to steal credentials. Self-XSS requires user interaction, where attackers trick users into executing scripts themselves by clicking deceptive links. While some popular browsers offer built-in protection against reflected and self-XSS, others rely on plugins such as NoScript to mitigate these vulnerabilities.

Internet security vulnerabilities, such as SQL injection flaws, can be easily exploited by attackers who systematically gather intelligence on a target website. Once an attacker identifies a vulnerability, they can craft an exploit to access sensitive information, including usernames and passwords, potentially compromising the entire database in a short amount of time. This highlights the ease and speed with which attackers can operate, emphasizing the importance of robust cybersecurity measures to protect sensitive data from falling into the wrong hands.
