As the article points out, if someone can inject Javascript into your checkout page, you're most likely also having other security issues.Still, and I'm pretty much being called an idiot every time I point this out: You should NEVER have the user enter credit card information on your site. That is something that is best left to your PSP. If you're Amazon or similar size, fine, I can accept that you most likely have the need resources. Anyone smaller should never interact with credit card information, leave it to Stripe, BrainTree, Paypal, someone trusted, with the resources to handle it.Also I'm not really surprised to see that it seem to be affecting Magento shops. Similarly to not accepting credit card directly: If you don't have the technical resource, don't run Magento. It's big and complicated, and you need to react fast when there's a problem. Contracting is an option, but expensive and the turn around time is a lot higher, especially if there's a critical error in Magento and everyone need the issue fixed right then and there.
