PayPal Payflow Pro active carding activity

UPDATED 2 April 2019

The PayPal Payflow Pro integration in Magento 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 Magento 2.1.x, 2.2.x, 2.3.x for Open Source and Commerce (on prem and cloud). The carding activity is inherent to the way Payflow Pro is integrated into shopping carts.

To help resolve these issues, we have provided new Composer packages to add Google reCAPTCHA or CAPTCHA to the Payflow Pro checkout form. We recommend installing these packages on all Magento 2 versions and editions.

The issue affects the following Magento versions:

  • Magento Open Source v2.1.x, 2.2.x, 2.3.x
  • Magento Commerce v2.1.x, 2.2.x, 2.3.x
  • Magento Commerce Cloud v2.1.x, 2.2.x, 2.3.x

Issue

Symptoms of these attacks include:

  • Your PayPal Payflow Pro account shows hundreds of fraudulent transactions identified
  • PayPal may suspend a Payflow Pro account due to incoming fraud transactions and charge substantial fees

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 Magento Admin.

Install Packages

Magento 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 Magento editions and versions:

  • Magento versions: 2.1.x, 2.2.x, 2.3.x 
  • Magento editions: Open Source and Commerce (on prem and cloud) and Commerce Cloud

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

We recommend installing and configuring Google reCAPTCHA in addition to installing any relevant Payflow Pro checkout form updates. This option provides an invisible check and multiple configuration options. 

Install Google reCAPTCHA and checkout form updates

The magento/module-paypal-recaptcha package contains integration with Google reCAPTCHA and Payflow Pro payment form updates. Even if you have the reCAPTCHA module installed and configured, we recommend you install this package.

Run the following commands to install it.

For Magento Commerce:

composer require magento/module-paypal-recaptcha
bin/magento module:enable Magento_PaypalReCaptcha
bin/magento setup:upgrade
bin/magento cache:clean

For Magento Commerce Cloud:

  1. Run the following command: 
    composer require magento/module-paypal-recaptcha
  2. Commit and push changes: 
    git add -A && git commit -m "Install Google reCAPTCHA"
git push origin %branch_name%
  3. Wait for deployment to complete.

Install checkout form updates for CAPTCHA

The magento/module-paypal-captcha package contains integration with the native Magento CAPTCHA module.

Run the following commands to install it:

For Magento Commerce:

composer require magento/module-paypal-captcha
bin/magento module:enable Magento_PaypalCaptcha
bin/magento setup:upgrade
bin/magento cache:clean

For Magento Commerce Cloud:

  1. Run the following command: 
    composer require magento/module-paypal-captcha
  2. Commit and push changes: 
    git add -A && git commit -m "Install CAPTCHA"
git push origin %branch_name%
  3. Wait for deployment to complete.

Configure Google reCAPTCHA or CAPTCHA

Having installed the package, configure Google reCAPTCHA (recommended) or CAPTCHA as described in the following docs:

The new checkout form option is:

  • Google reCAPTCHA: Use in PayPal PayflowPro payment form 
  • CAPTCHA: Payflow Pro

PayPal support and contacts

Please contact PayPal Payflow Merchant Support to learn more about Fraud Protection Services. You can request the PayPal Support team to enable Basic Fraud Protection Services filters to provide the tightest control possible over payments so that you can automatically deny payments that are likely to result in fraudulent transactions and accept payments that are not typically a problem. Please note, that once you turn on PayPal Fraud Protection Services filters, transactions can take up to 2 hours to settle.

For additional information, see PayPal’s KB “Magento has contacted me about my Payflow Pro integration. What do I need to do?”.
