The correct answer is C, as mapping scenarios are helpful in mitigating the weakness of not generating alerts when activity is consistently abnormal over a long period of time. Mapping scenarios are used to compare a customer's activity with their expected activity based on their profile, risk rating, or historical behavior1. By using mapping scenarios, the organization can identify customers whose activity deviates significantly from their normal or expected patterns, and flag them for further investigation. Mapping scenarios can also help detect changes in customer behavior over time, and alert the organization of any potential money laundering or terrorist financing risks.

This is an emerging risk associated with cyber-enabled fraud because the use of false identities and documents can allow criminals to disguise their activities and evade detection. In such cases, the name and address provided on the account may not match the name and address on the government-issued documentation. This discrepancy can be difficult to detect, making it a potential risk for financial institutions.
