What is the attack?Over 100,000+ sites have been impacted by a supply chain attack involving the Polyfill.io service. Polyfill is a popular tool used for enhancing browser capabilities by hundreds of thousands of sites to ensure that all website visitors can use the same codebase for unsupported functionality. Earlier this year, the polyfill.io domain was purchased, and the script was modified to redirect users to malicious and scam sites.What is the recommended Mitigation?Given the confirmed malicious operations, owners of websites using polyfill.io are advised to remove it immediately and search their code repositories for instances of polyfill.io. Users are also advised to consider using alternate services provided by Cloudflare and Fastly.What FortiGuard Coverage is available?FortiGuard Labs’ research team is investigating the coverage and has blocked all the known Indicators of compromise (IoCs).
