Google Hosted Libraries
Google Hosted Libraries is a CDN (ajax.googleapis.com) that serves popular open-source JavaScript libraries such as jQuery and Angular. ScanMalware detects it from those asset URLs.
Loading libraries from a shared CDN is a supply-chain dependency: the site trusts the hosted file to be unmodified. Verifying that file against known-good fingerprints guards against tampering.
