Fraud is evolving fast, and fraudsters are exploiting the fragmentation of the financial ecosystem to deceive victims and outpace bank anti-fraud teams. Detecting fraud schemes and protecting victims requires collaboration across financial institutions, trusted partners such as telecom operators and technology platforms, and public authorities.
