Polyfill supply chain attack hits 100K+ sites

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.

    I’ve been using noscript for years.

    Yeah, it took me about that long to get my regular websites working right too. And then i had to reinstall for unrelated reasons and all that customisation was gone.
