Dynamic fraud intervention machine

A non-transitory machine-readable storage medium comprising instructions that, when executed by one or more processors of a machine, cause the machine to perform operations comprising:

• detecting a request to execute a transaction specified by a first set of user inputs;
• determining, based on the first set of user inputs that specified the transaction, that the request to execute the transaction is to be verified with a corresponding challenge prompt, the determining including:
• calculating a fraud likelihood score of the request based on the first set of user inputs that specified the transaction;
• and
• determining that the fraud likelihood score of the request is within a first range of fraud likelihood scores between a second range of fraud likelihood scores and a third range of fraud likelihood scores, the second range corresponding to presence of fraud and the third range corresponding to absence of fraud;
• generating, by the one or more processors, the corresponding challenge prompt to verify the transaction;
• causing presentation of the corresponding challenge prompt, a second set of user inputs being received in response to the presentation of the corresponding challenge prompt;
• and
• generating an indication of whether the request to execute the transaction is verified based on the second set of user inputs.

A system comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by at least one processor among the one or more processors, cause the system to perform operations comprising:
• detecting a request to execute a transaction specified by a first set of user inputs;
• determining, based on the first set of user inputs that specified the transaction, that the request to execute the transaction is to be verified with a corresponding challenge prompt the determining including:
• calculating a fraud likelihood score of the request based on the first set of user inputs that specified the transaction;
• and
• determining that the fraud likelihood score of the request is within a first range of fraud likelihood scores between a second range of fraud likelihood scores and a third range of fraud likelihood scores, the second range corresponding to presence of fraud and the third range corresponding to absence of fraud;
• generating, by the one or more processors, the corresponding challenge prompt to verify the transaction;
• causing presentation of the corresponding challenge prompt, a second set of user inputs being received in response to the presentation of the corresponding challenge prompt;
• and
• generating an indication of whether the request to execute the transaction is verified based on the second set of user inputs.
