    • /shipping_address/distance_to_ip_location

Updates to minFraud Alerts

We recently made some updates to minFraud alerts, which notifies minFraud users about previously low-risk transactions that are now high-risk due to updated information. Learn more on our blog.

Normalize Emails Before Hashing for Improved minFraud Scoring

February 22, 2021

The client APIs for minFraud Score, Insights, and Factors now normalize emails prior to hashing them for improved risk scoring. Email normalization ensures that minor, inconsequential differences in the email input (i.e., jadoeisonline@yahoo.com and jadoeisonline-12345@yahoo.com) do not result in minFraud treating these as different email addresses.

Our client APIs for minFraud Score, Insights, and Factors have been updated to support email normalization so you may need to refresh yours in order to get automatic email normalization. If you interface directly with our REST API or use minFraud Legacy, we recommend that you normalize email addresses prior to hashing. Please see our developer’s site for guidance on how to normalize emails.

New output IP risk reasons

February 3, 2021

The ip_address/risk_reasons output is now available. minFraud Insights and minFraud Factors customers can now see reason codes associated with the IP risk score for high risk IP addresses. When the IP risk score is high, the field may be populated with one or more of the following reason codes:

  • ANONYMOUS_IP – The IP address belongs to an anonymous network. See /ip_address/traits for more information.
  • HIGH_RISK_DEVICE – A high risk device was seen on this IP address in your past transactions.
  • HIGH_RISK_EMAIL – A high risk email address was seen on this IP address in your past transactions.
  • BILLING_POSTAL_VELOCITY – Many different billing postal codes have been seen on this IP address in your past transactions.
  • EMAIL_VELOCITY – Many different email addresses have been seen on this IP address in your past transactions.
  • ISSUER_ID_NUMBER_VELOCITY – Many different issuer ID numbers have been seen on this IP address in your past transactions.
  • MINFRAUD_NETWORK_ACTIVITY – Suspicious activity has been seen on this IP address across minFraud customers.

If the IP risk score is low, the risk_reasons field will be blank. Our client APIs have been updated to support this output so you may need to refresh yours in order to see the new output if you are not interfacing directly with our REST API.

Change to Vodafone Germany ISP name

January 22, 2021

On Monday, January 25 we will be updating MaxMind products and services with ISP data to consolidate naming conventions for Vodafone Germany. We will now return either Vodafone Germany Cable, Vodafone Germany DSL, Vodafone Germany Business, or Vodafone Germany. Previous values were Vodafone GmbH, Vodafone Germany, and Vodafone DSL. We are updating these values to more accurately reflect the type of connection that the IP address is associated with.
