Using Custom Inputs to Refine Your Response to Fraud

Online fraud is a complex, hard to detect, and constantly evolving type of crime with serious business consequences. While many e-commerce merchants are looking for new ways to engage with customers, fraudsters are also looking for new ways to exploit them. In a way, every touchpoint you create - from buy online/pick up in store options to social click-to-buy ads, mobile shopping to loyalty rewards programs - is another opportunity for cybercriminals to bypass your fraud screening.

Fraudsters are clever. They will often make multiple attempts to infiltrate your systems before being detected. To determine the most effective response to stopping their ever-evolving tactics, you first have to look at what the transactional evidence is telling you. And each transaction may require a different analysis and approach.

Introducing Custom Inputs

minFraud Score, minFraud Insights, and minFraud Factors customers can now use Custom Inputs to create Custom Rules that are fine-tuned by YOU to identify fraudulent activity in your specific business environment. Custom Inputs can be used during review of transactional details in support of your minFraud queries to help identify suspicious activities and prevent chargebacks, card association fines, and false positives.

Custom Inputs can help you…

  • Extend minFraud service features to capture data points specific to your experience with fraud
  • Use data points you define to automatically accept, reject, or send transactions to manual review
  • Enable review of custom data points in the context of minFraud service data points

We currently support Custom Inputs using the following data types: string, Boolean, number, and phone number.

Custom Inputs and Loyalty Program Fraud

Let’s consider how you can use Custom Inputs to help prevent a type of fraud that’s becoming increasingly popular with cybercriminals: Loyalty Program Fraud.

Loyalty programs are an excellent way to strengthen your relationship with customers. In fact, loyalty programs in the U.S. alone achieved double-digit growth (to 3.8 billion members) in 2017. Loyalty points can be spent like cash, making them highly appealing to fraudsters. Data-profiling solutions that monitor transactions for suspicious activities commonly linked to Loyalty Program Fraud can help prevent that fraud from ever occurring in the first place.

Seeking transactional irregularities with loyalty programs, you can use Custom Inputs to create Custom Rules that target unusual spending patterns, warehouse timezones, different IP addresses, or any other data that may mean a fraudster has hijacked your customer’s account.

For example, let’s imagine that you run a loyalty rewards program offering Amazon gift cards for 10% off the regular price. In that scenario, customers can apply up to $10 in loyalty rewards to the purchase of a $100 gift card in your loyalty store. You may notice that someone is trying to buy those cards for less than the full discounted price. That “someone” may in fact be a fraudster attempting to use a stolen credit card number to purchase gift cards only available in your loyalty program and which are easily resold and converted to cash.

In order to purchase the highly desirable Amazon gift cards, a fraudster acquires loyalty points on your site by making fraudulent purchases or makes a purchase in your loyalty store without applying any loyalty rewards at all. Simply put:

  • Good customers buy Amazon gift cards from loyalty store with full discount ($100 gift card for $90 by applying $10 in loyalty rewards to the purchase)
  • Fraudsters buy Amazon gift cards from loyalty store with less than full discount ($100 gift card for $98 or even full price for the gift cards. Fraudsters don’t care what they pay for the gift cards because they are using stolen credit cards.)

Creating a parameter “loyalty store price” using the “number” data type, you can create a Custom Rule to manually review a purchase if the purchase price of the gift card in your loyalty store is greater than the loyalty program’s maximum discounted price. Your Custom Rule would look like this: If price (input) < loyalty store price (Custom Input), THEN manual review. By doing that, your fraud analyst can take a better look at the transaction, reviewing it with additional intelligence returned by the minFraud Network, to determine if the customer is actually a fraudster in disguise.

That’s not all. Keep in mind, you create your own Custom Inputs. So, you could also pull from the intelligence within the minFraud service to create a Custom Rule that reduces your manual review times by automatically resolving known high risk transactions. Borrowing from the loyalty program example above, your Custom Rule would be: If price (input) < loyalty store price (Custom Input) AND riskScore > 20, THEN reject.

Those are just a few examples of how you can use Custom Inputs as part of your fraud prevention strategy. You can create up to 24 Custom Inputs for use with Custom Rules. With Custom Inputs fueling the creation of Custom Rules combined with results from the minFraud Network, your risk analysis can stay ahead of fraudsters.
