The article highlights the growing threat of fraud in fintechs, with synthetic identities being the fastest-growing form of financial crime. Fraudsters are using stolen credentials and dark web marketplaces to steal data, making it easier for them to create fake identities and take over accounts. Fintechs must combat this by expanding their risk assessment signals through a network-based approach, incorporating insights from other sources within the ecosystem. This can be achieved through verifying customer identities during sign-up, monitoring for risky behavior and transactions on an ongoing basis, securing transactions with machine-learning-powered risk engines, and leveraging a connected network to build a safer digital finance ecosystem. By using these strategies, fintechs can fight fraud at scale and protect their customers.
