At the end of May this year, a number of writers were subject to what appears to be a coordinated Shopify bot attack on their stores, resulting in many hundreds of fraudulent orders being placed. Several of these authors were ALLi members who got in touch with their experiences so that we could raise awareness.

Experiencing an event like this is obviously highly traumatic, but the issue that the writers who have been in touch with ALLi wanted to be raised is how Shopify subsequently dealt with the efforts to clean up after the attack, and the financial consequences this has left for those writers affected.
In this piece, I want to outline what happened, how Shopify responded, and highlight things other authors need to be aware of.
A Coordinated Attack and Mixed Responses
The event itself involved multiple authors’ Shopify stores being targeted, on May 27, with hundreds (in one case we know of, more than 2,000) of fraudulent attempts to buy ebooks. Shopify’s bot protection security seems to have blocked a substantial proportion of these, but hundreds still got through.
Authors responded by refunding the payments that got through. They did this both manually and using Shopify’s automated refund system. But the process left authors out of pocket for the original transaction fees. (In at least one instance, Shopify offered a goodwill gesture of a Shopify credit for this amount, but that had not materialized by the time the author contacted ALLi.) And in some cases, authors were also liable for chargeback fees of $15 per instance because of the length of time it took Shopify to process the refunds.
I have been sent transcripts of customer service conversations, and these highlight several points. First, Shopify seems to be aware that there was a large-scale fraudulent attack on its checkout system. Second, while Shopify does not refund transaction fees for regular refunds, customer service representatives stated that where there is known fraud, store owners would not bear the costs of transaction fees. (Shopify’s documentation, however, suggests that this is not the case and that credit card fees for fraudulent activity will not be refunded. What Shopify recommends is that store owners activate manual handling of orders so that an order will not go through until it has been approved by the store owner.) Third, Shopify and its representatives struggled to maintain a consistent understanding of sellers’ cases and a consistent application of their own stated policy.
Risks for Indie Authors
There are further aspects to this, such as the fact that this seems to have been linked to fraudulent email signups, causing difficulty for those with mailing list signup limits.
For clarification, Shopify’s most stringent anti-bot protection is only available to those with Shopify Plus accounts, which may not apply to a lot of indie authors, further exposing indies to financial risk. As one of the writers who contacted ALLi put it, they thought that by using a large, respectable platform like Shopify, they would be protected from financial risk in relation to exactly this kind of incident. They were disappointed to discover that seems not to be the case.
What are the key takeaways from this? First, to put in place all the anti-bot protection you can on the plan you have. Second, to do what the authors who contacted us did: refund fraudulent transactions straightaway and get in touch with Shopify’s support immediately. But it is also valuable to raise the issue in author forums, as these authors did. Doing that enabled them to establish that this was a coordinated attack—information they were then able to share with Shopify.
Shopify was contacted for comment but did not respond.

This is still going on. I was hit with 50+ fraudulent purchases in July, and after that mess I now only have free books on my site. I will also not be renewing with Shopify and will close my store before I get charged my annual store fee again.
