Shopify Fraud Inquiry - Potential Data Breach and Fraudulent Transactions

Shopify Fraud Inquiry

Hi, First of all, I do not have a Shopify store. I've used the platform mainly as a consumer to purchase products. Second, I use a well-known virtual card service for online purchases (, which allows me to maintain separate cards per vendor/merchant.

The situation I find myself is the following. On July of 2023, I made a purchase through a Shopify-integrated store (Vendor A) for which I created a unique Privacy card. After this purchase was completed, I paused the card and did not buy anything else from this Vendor A. Then, yesterday I got a notification from Privacy stating that the card had two transactions declined while paused. Both transactions originated from a vendor which I've never used before (Vendor B) who doesn't seem to use Shopify's platform to sell products.

Why am I reaching out to Shopify? Well, I can rule out Vendor A for two reasons. First, and please correct me if I'm wrong, stores do not have access to the customer's credit card information (number, expiration, CVV). Second, the card in question is tied to Vendor A and CANNOT be used anywhere else. So, the only thing that comes to mind is an internal leak of customer information or at least a bad actor.

I know this is a very sensitive matter, so please feel free to reach out to me directly and I will provide exact transactional and vendor information.

P.S. I am posting this message here because I could not find a suitable communication channel for it (email, support, etc.). But, I would greatly appreciate it if someone could help me route this message or point me to the correct location.

Thank you for your attention to this matter, and I look forward to any help provided.
