New account fraud, a prevalent challenge for banks and fintechs, involves the creation of multiple accounts using false or stolen information to exploit financial systems, resulting in significant financial and compliance risks. Unlike account takeover attacks, new account fraud is often less detectable and offers fraudsters a relatively low-risk, high-reward opportunity to gain unauthorized access to funds. The advent of generative AI, the availability of stolen credentials on the dark web, and the use of sophisticated bots have made it easier for fraudsters, including teenagers and young adults, to engage in this type of fraud. The impact on financial institutions includes monetary losses, reputational damage, compliance risks, and restricted growth. However, fintechs are employing strategies like multi-factor authentication, machine learning, blocklists, and advanced device intelligence platforms to combat this fraud. These measures aim to identify suspicious behavior and prevent the creation of fraudulent accounts by leveraging techniques such as device fingerprinting and anomaly detection during the sign-up process.
