Ask HN: How do I stop card testing attacks on my Stripe account?
3 by tempaccount3333 | 1 comments on Hacker News.
For the past several months I have been getting hit with several card testing attacks. I sell a product with a subscription (which is processed via Stripe). The problem is that everytime this occurs I have to manually go into my account and determine if it is a card testing attack and then if it is then I have to refund and block the payment. Not a big deal if it happens once or twice but has been happening very frequently on my account. I've tried everything I can on my end but it's very limited what I can do since they don't even go through my website (I use Stripe Checkout, which they say is excellent protection against card attacks - which seems untrue to me). They simply get my public key (which I've rotated) and create their own checkout session. I've reached out to Stripe SEVERAL times and it is really annoying that they are unable to stop it. What can I do, short of switching to PayPal or another provider? Thanks!
