Hi,

I am sorry to hear that.

As a first step, I’d recommend implementing a 3D secure verification on your site, so that when adding a card the customer will need to go through the verification. This will add an extra security layer on your site. More information is below:

• 3D Secure
• Guide to WordPress Brute Force Protection

Let us know if you need further assistance.

Why does this plugin allow infinite payment attempts with no rate limiting at all?

3DS is not a solution, and this plugin shouldn’t require another plugin to avoid security and performance issues.

Cheers,

Jason

Hi @galapogos01 ,

Why does this plugin allow infinite payment attempts with no rate limiting at all?

There isn’t a rate limiting added by default as that may affect high traffic stores (where all those payment attempts would be valid).

We have more guidance on preventing card testing here, although those require additional plugins as well.

Sorry your logic makes no sense.

I had 25,000 payment attempts against a single order from a single IP. This has nothing to do with high volume sites.

Your customers and Braintree themselves would appreciate a proper solution to this very real issue.

Hi,

I understand your concern.

To set up rules to prevent payment retries after a specific number of attempts, you can use this free plugin:

• Woo Manage Fraud Orders

Please note it is a plugin not supported directly by us, feel free to reach their support in case of interest from your side. This will add a second security layer to your business.

Also, you can turn on?Fraud Protection Advanced,?by login to your Braintree account, then navigate to?Settings > Fraud Management, make sure to enable the Fraud Protection Advanced. More information is below:

Let us know if there are any questions.

I already have fraud prevention turned on.

I don’t understand why you think it’s okay to use a third party plugin to solve problems with your own. Your customers are asking you to solve this issue in your plugin. Can you please listen to our request and add this to your development backlog as a high priority?

Hi Jason. Welcome to “WC core security gaps victim support group”.

You should first join #security channel on WooCommerce Slack, here’s an invite link https://join.slack.com/t/woocommercecommunity/shared_invite/zt-1uetvimgj-MsoAFa5HbsyFxjcG2Dnjtg

I drove creation of this channel after my WC site went through the same attack you’re experiencing.

WC core currently ships zero protection for this abuse in core. There’s no security team that I know of, even, so it’s not surprising. This attack is gateway-agnostic, my experience with Stripe plugin is described at https://github.com/woocommerce/woocommerce-gateway-stripe/issues/918#issuecomment-1335918154

We need to join efforts to get this situation improved.

Thanks for letting me know. I guess WC Core should be the ones fixing this.

We have just experienced this exact same issue, we are using Stripe for payments. Not sure what to do about it at the moment other than to block the IP and hope they are not smart enough to change IP’s!

AFAICT core developers have done nothing to protect from this attack over past months. It needs more drive and demand.

#security channel did get started on WooCommerce Slack.

Your primary defense still is to have a captcha on checkout screen, do not accept orders without passing it.

How can we escalate this with the core security team?

i @galapogos01 ,

How can we escalate this with the core security team?

I’d recommend opening an issue on WooCommerce GitHub to start a discussion with the development team.
