Stop WooCommerce fake orders and card-testing attacks
A card-testing run can cost you chargeback fees and your payment processor in a single afternoon. QWeb Spam Shield detects checkout abuse in real time and protects your store standing before the damage is done.
How a card-testing attack hurts your store
Fraudsters run thousands of stolen card numbers through any WooCommerce checkout they can find, looking for the ones that still work. Each attempt can cost you a fee, and a burst of failed payments is exactly the signal Stripe and PayPal watch for. Processors have placed rolling reserves on, raised rates for, and outright terminated merchants over this, often with little warning.
How Spam Shield defends checkout
- Velocity and burst detection spots a single source firing many checkout attempts and stops the run in real time.
- Reputation and behaviour checks flag known-bad IPs, mismatched details and disposable emails at the order stage.
- Real customers protected. A genuine shopper retrying a declined card is flagged for review, not hard-blocked, so you never turn away a real sale.
- Outbound Mail Guard stops a flood of order-notification emails from wrecking your domain reputation during an attack.
Protect your processor standing
The cheapest fraud is the one that never reaches your gateway. By cutting off card-testing bursts at the checkout, Spam Shield keeps your failed-payment ratio low and your merchant account in good standing, which is far cheaper than recovering it later.
