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.
That’s not how systemic problems work.
This is probably one of the most security ignorant takes on here.
People will ALWAYS fuck up. The world we craft for ourselves must take the “human factor” into account, otherwise we amplify the consequences of what are predictable outcomes. And ignoring predictable outcomes to take some high ground doesn’t cary far.
The majority of industries that actually have immediate and potentially fatal consequences do exactly this, and have been for more than a generation now.
Damn near everything you interact with on a regular basis has been designed at some point in time with human psychology in mind. Built on the shoulders of decades of research and study results, that have matured to the point of becoming “standard practices”.
