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.

    Flash ran as a browser plugin (as in not an extension, but a native binary that is installed into the OS and runs beside the browser, we basically don’t do this for anything now)

    Flash was pretty much on weekly security bulletins in the final years, arbitrary code execution and privilege escalation exploits were common, that’s why Adobe killed it.

    Flash was never safe and comparing JavaScript to it as a greater risk shows you’ve not fully understood the threat model of at least one of the two.
