cdn.polyfill.io on Internet Provider Website

[Brdn]

Hello,

I was paying the bill for my internet provider and noticed that BrowserGuard had blocked something on the site as Malware. I looked at the information and found that BrowserGuard had flagged a cdn.poylfill.io/ link as malicious, labelling it Malvertising. I looked into it further and found several websites reporting on a Polyfill Supply Chain attack, and several vendors on VirusTotal also listed the link as malicious.

Since this necessarily involved providing card details in order to pay my internet bill, is there a risk that my card info is now compromised and I should look at getting a new one?

Thank you,

Please provide a URL from which you get a warning. Thanks

Thank you for your response.

The blocked URL is <https://cdn.polyfill.io/v3/polyfill.min.js?/features=es6,Set,Array.prot...>

This is as much of the link that BrowserGaurd will let me view.

I also got a warning that cdn.polyfill.io was blocked on this site after typing in the above URL.

Cheers,

The domain is legitimately blocked.

Anyway, as for your card I believe it is not compromised, but I don't know which website it is, so best to check that with your internet provider.

Thanks!
