Website Administrators: Remove Polyfill.io Service to Avoid Malware Risks

Attention all website administrators! If you're currently using the Polyfill.io service on your site, you need to remove it immediately to prevent malware from infecting your visitors. The service, which was created to help provide modern web functionality to older browsers, has recently been found to be serving malware.

Polyfill.io was sold to a Chinese company back in February 2024, and since then, cybersecurity experts have warned that it could be used for supply chain attacks. Cloudflare and Fastly have since created their own trusted versions of the service, but many sites are still using the original service, which is now considered a security risk.

Google Warns of Malicious Redirects

Even Google has issued warnings about Polyfill.io, stating that no website today requires any of the polyfills in the service's library. Additionally, the tech giant has notified affected advertisers that their landing pages may be redirecting visitors to potentially harmful websites via the compromised Polyfill.io service. Other third-party web resource providers, such as Bootcss.com, Bootcdn.net, and Staticfile.org, have also been identified as sources of these malicious redirects.

To protect your website's visitors and your own online reputation, it's crucial to remove Polyfill.io and switch to a safer alternative. Don't let your site become a gateway for cybercriminals to attack unsuspecting users. Act now and ensure the safety of your online community.

Protect Your Site with Trusted Services

Remember, keeping your website secure is essential in today's digital landscape. By using trusted services and staying informed about potential threats, you can maintain a safe and enjoyable experience for your audience. Don't wait until it's too late - remove Polyfill.io from your site and explore alternative solutions from reputable providers like Cloudflare and Fastly.
