An Abandoned CDN Domain Was Re-Registered. Thousands of Sites Still Call It.
A content delivery network (CDN) domain expired and was re-registered by a new owner in July 2025, while thousands of websites and code repositories retained hard-coded references to the old CDN hostnames. The new registrant now controls the infrastructure that these sites attempt to load assets from, creating a potential attack surface.
Why it matters: Website operators and developers relying on the expired CDN domain face supply chain compromise risk if the new owner serves malicious content; practitioners should audit for hard-coded external dependencies and enforce subdomain monitoring.
