PayPal Payflow Pro active carding activity

UPDATED 2 April 2019

The PayPal Payflow Pro integration in Adobe Commerce is being actively targeted by carding activity, where attackers attempt hundreds of $0 transactions with stolen credit cards to check the card’s validity.

The activity currently targets versions of this Payflow Pro integration that were included in Adobe Commerce 2.1.x, 2.2.x, 2.3.x for Magento Open Source and Commerce (on-premises and cloud). The carding activity is inherent to the way Payflow Pro is integrated into shopping carts.

The issue affects the following Adobe Commerce versions:

Symptoms of these attacks include:

Solution

To help protect from these attacks, we advise adding Google reCAPTCHA (recommended) or CAPTCHA to the Payflow Pro checkout form. This includes installing the Composer packages and configuring Google reCAPTCHA or CAPTCHA in the Commerce Admin.

Install Packages

Adobe created two package options to add Google reCAPTCHA and/or CAPTCHA to the Payflow Pro checkout form. Installing one of these packages will update current installations and add an option that can help enhance this security to the Payflow Pro checkout form.

These packages are compatible with the following Adobe Commerce deployments and versions:

Adobe Commerce (all deployment methods) and Magento Open Source 2.1.x, 2.2.x, 2.3.x

Installation requires CLI commands to your Adobe Commerce instance. Developer assistance may be required.

Please contact PayPal Payflow Merchant Support to learn more about Fraud Protection Services.
