I am experiencing a sustained card-testing bot attack on my store with 225+ fraudulent $2 orders in the past month.
They use Shopify’s built-in cart URL schema to skip directly to checkout without loading a single storefront page.
Abandoned checkout emails are sent to bogus or disposable email addresses This results in high bounce rates High bounce rates damage sending reputation
Approximately $0.38 in unrecoverable transaction and processing fees per fraudulent order.
Bot blocking apps from the Shopify app store do not help with this.
