Malware Threat from Polyfill.io Domain

Over 100,000 websites are at risk of malware infection due to scripts from the polyfill.io domain being compromised by a Chinese organization. Security firms are urging website owners to remove JavaScript code from the domain, which was once known for providing polyfills but is now distributing hidden malicious code. Google has blocked ads on affected sites and notified owners about the issue, as more than 100,000 websites have already been compromised. Funnull, a suspected Chinese CDN operator, acquired the domain in February, raising concerns about potential affiliations with Chinese entities.
