JavaScript tagging is a method used to detect and track malicious bot activity on websites by analyzing user behavior, mouse movements, scroll patterns, and other interactive elements. This technique involves embedding small pieces of JavaScript code into web pages that allow site owners to gather data and differentiate between human users and automated bots. By tracking specific behaviors that are difficult for bots to replicate but natural for human users, such as interaction speeds, mouse movements, and overall behavior, websites can identify potential bot activity and take measures to prevent it. However, JavaScript tagging has its limitations, including privacy concerns and performance overhead, and should be used in conjunction with other detection techniques to provide a robust defense against automated threats. Implementing behavioral analysis with other security measures can help protect websites from scraping, fraud, and other malicious activities, ensuring a safe and seamless user experience.
