Third-Party JavaScript Security: When Your Website Loads Someone Else's Code สำหรับองค์กรไทย

Modern websites load dozens of third-party JavaScript files — analytics, marketing pixels, chat widgets, social media embeds, A/B testing tools. Each runs with full access to the page content, including form data, session tokens, and user interactions. Magecart-style attacks exploit this by compromising a single third-party script to harvest payment cards from thousands of websites. Assessment covers: inventorying all third-party scripts, evaluating each provider's security posture, implementing Content Security Policy to restrict script sources, and using Subresource Integrity to detect modified scripts.
