953 Magento Stores Hit by Scanner-Evading JavaScript Skimmer Campaign

Engineer — Plan: If you run Magento, audit all CMS blocks for unauthorized JavaScript snippets and review admin access logs for changes since July 2025; confirm no rogue loader code is being served to shoppers from page templates.
SOC/IR — Plan: Build or tune detections for unexpected CMS block modifications and scanner-evading JavaScript loader injections in web application logs; consider hunting for this pattern in any Magento estate back to July 2025.
Leader — Learn: A long-running skimmer campaign touching nearly a thousand stores is a useful risk-register input for any organization running Magento e-commerce; relevant to PCI DSS scope reviews but not a board-level systemic event today.
