The new Chinese owner of the popular Polyfill JS project injects malware into more than 100 thousand sites.

The polyfill.js is a popular open source library to support older browsers. 100K+ sites embed it using the cdn.polyfill.io domain. Notable users are JSTOR, Intuit and World Economic Forum. However, in February this year, a Chinese company bought the domain and the Github account. Since then, this domain was caught injecting malware on mobile devices via any site that embeds cdn.polyfill.io. Any complaints were quickly removed (archive here) from the Github repository.

    We know, but we don’t have time to change. We have another site waiting to get slammed out as soon as the one we’re working on, which was underfunded with a ridiculous timeline goes live.

    There’s still a fair bit of “my nephew makes websites, it can’t be that [hard, expensive, time consuming], oh and by the way, e we need a way to edit every word and image on the site, that both our intern and barely literate CEO can understand, even though we’re literally never going to edit anything ever.”
