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:
- Adobe Commerce on-premises v2.1.x, 2.2.x, 2.3.x
- Adobe Commerce on cloud infrastructure 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 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.
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 Adobe Commerce on-premises:
composer require magento/module-paypal-recaptcha
bin/magento module:enable Magento_PaypalReCaptcha
bin/magento setup:upgrade
bin/magento cache:clean
For Adobe Commerce on cloud infrastructure:
-
Run the following command:
code language-bash composer require magento/module-paypal-recaptcha
-
Commit and push changes:
code language-bash git add -A && git commit -m "Install Google reCAPTCHA" git push origin %branch_name%
-
Wait for deployment to complete.
Install checkout form updates for CAPTCHA
The magento/module-paypal-captcha
package contains integration with the native Adobe Commerce CAPTCHA module.
Run the following commands to install it:
For Adobe Commerce on-premises:
composer require magento/module-paypal-captcha
bin/magento module:enable Magento_PaypalCaptcha
bin/magento setup:upgrade
bin/magento cache:clean
For Adobe Commerce on cloud infrastructure:
-
Run the following command:
code language-bash composer require magento/module-paypal-captcha
-
Commit and push changes:
code language-bash git add -A && git commit -m "Install CAPTCHA" git push origin %branch_name%
-
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:
- Google reCAPTCHA in our user guide.
- CAPTCHA in our user guide.
The new checkout form option is:
- Google reCAPTCHA: Use in PayPal Payflow Pro 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.
