Claim 12:
13. A non-transitory computer-readable medium with computer-executable instructions stored thereon executed by an electronic processor to perform a method of generating a fraud risk score for a third party provider (TPP) transaction, comprising:
setting an adjustable predetermined threshold to a predetermined value;
receiving from an electronic device configured to manage an online resource, a request to generate a fraud risk score for a TPP transaction;
determining a frequency-recency-monetary value feature, a reputation feature, and a rule feature for the TPP transaction;
when there is a first change in a distribution of values for the frequency-recency-monetary value feature across users interacting with a TPP, determining that an anomalous event is occurring and adjusting the adjustable predetermined threshold based on the change in the distribution of values for a frequency-recency-monetary value feature;
when there is a second change in the distribution of values for the frequency-recency-monetary value feature across users interacting with the TPP, determining the anomalous event is over and reverting the adjustable predetermined threshold to the predetermined value;
using the frequency-recency-monetary value feature, the reputation feature, and the rule feature as input for a machine learning model, executing the machine learning model to generate a blended fraud risk score;
when the blended fraud risk score is above the adjustable predetermined threshold, determining that the TPP transaction is fraudulent; and
sending an indication of whether the TPP transaction is fraudulent to the electronic device, wherein the electronic device allows or denies access to the online resource based on the indication of whether the TPP transaction is fraudulent.
