Problem
Third-party JavaScript scripts pose a significant security risk to websites, as they have unrestricted access to user browsers and can be compromised to rewrite page content, steal sensitive data, or redirect users to malicious sites. Website owners often lack visibility into the behavior and changes of these scripts, making it difficult to detect and prevent attacks like Magecart and other forms of script hijacking. Furthermore, unoptimized scripts can negatively impact website performance, leading to slower loading times and a degraded user experience.
