Session overview

Carding attacks are a growing threat to WooCommerce stores, allowing fraudsters to test stolen credit card details at your checkout. These attacks can result in hundreds or even thousands of spam orders and unauthorized transactions, chargebacks, and potential account suspensions from payment providers. If left unchecked, they can lead to financial losses, reputational damage, and increased security risks for your store.

In this webinar, we’ll explore what carding attacks are, why they target WooCommerce checkouts, and the best strategies to prevent them. You’ll learn how these automated bots or manual attackers operate, how to detect unusual transaction patterns, and what security measures you can implement to safeguard your store.

What You’ll Learn:

Understanding Carding Attacks: How fraudsters use automated scripts to test stolen credit card details.
Why WooCommerce Checkouts Are Targeted: The vulnerabilities that make WooCommerce stores a prime target.
Detecting the Warning Signs: How to spot sudden spikes in failed transactions, unusual traffic, and suspicious activity.
Preventative Measures: Best practices, from CAPTCHA and rate limiting to fraud prevention plugins and payment gateway settings.
How to Handle an Ongoing Attack: Steps to mitigate damage, block malicious traffic, and report fraudulent activity.

This session is perfect for WooCommerce store owners, developers, and security-conscious professionals looking to protect their WooCommerce business from fraud. Join us to gain actionable insights and keep your checkout safe from carding attacks!

WooCommerce Failed Orders Monitor PHP Snippet

We talked about this solution at the very end of the masterclass, and I still believe it’s your best bet against carding attacks. I will turn this into a mini plugin at some stage!

I promised you I was going to complete it, so here you go. With a simple snippet, you simply tap into the “failed” order status, which should be VERY rare in your store, and if there are too many of them within the last 10 minutes, the store automatically goes into “Lock down” mode.

You can find the full version of this snippet at WooCommerce: Failed Orders Monitor & Temporary Lockdown
