Author note: This blog post style is trying something new. Instead of trying to write long-winded about a subject I’ve researched, I wanted to give a real-time reaction to something I just have read.

These micro-blogs will be much less formal and may contain social / political commentary. The goal is for these to serve as an online bookmark for things I find interesting and my opinion on them.

It’s interesting what happens when you start offering a “free” hit of your inference. This bit is particularly concerning given that the implication of these bad actors using your platform is you risk your reputation as a merchant.

I wasn’t surprised about the overdraft feature being abused. This was something we were aware of and treated as a conscious trade-off between convenience and risk of abuse.

The bigger issue was that this made me realize that a malicious actor could abuse our system for card testing. That’s a widespread problem and one that will get your Stripe account flagged. When researching this problem, I didn’t find many effective solutions, so I wanted to dedicate part of this blog post to sharing what I learned.

The author goes on to mention a few different mitigation strategies they have implemented with varying degrees of success. Noting that JA4 TLS fingerprinting was most effective.

Be viligante folks.
