Stop Stripe card-testing attacks on WooCommerce
A card-testing run sends a flood of small Stripe charges through your checkout to find which stolen cards still work. The failed and disputed payments are exactly what Stripe watches for. QWeb Spam Shield stops the burst at your checkout before it reaches Stripe.
Works with Stripe
Why card testing puts your Stripe account at risk
Stripe Radar catches a lot, but the attempts still hit your account, and a spike in failed payments and disputes can lead to a rolling reserve or a closed account. The cheapest fraud is the one that never reaches your gateway in the first place.
How Spam Shield protects your Stripe checkout
- Velocity and burst detection spots one 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.
- Works alongside Stripe Radar by cutting the volume that ever reaches it, keeping your failed-payment ratio low.
Protect your account standing
By stopping the attack at the checkout, Spam Shield keeps the dispute and failure signals down, which is what keeps your Stripe account in good standing. That is far cheaper than getting a reserve released later.
