Broadcom Inc. launched Arcot Scam Defense, a feature of Arcot by Broadcom aimed at blocking social engineering fraud in card-not-present transactions.
Fraud attempts have grown across financial institutions, with nearly half a billion dollars reported over the past 12 months on successfully authenticated challenges. Fraudsters now impersonate trusted brands and institutions to persuade cardholders to reveal passwords or complete step-up authentications, shifting attention from security systems to the customers themselves.
After a cardholder completes a 3-D Secure challenge with a one-time password or biometric, a financial institution's primary risk models treat the transaction as legitimate and approve it. Arcot Scam Defense instead evaluates transaction information, device intelligence, historical behavior, and the challenge interaction together, including checkout and authenticating device discrepancies, delayed OTP entry, alternative authentication methods, and physical distance between devices.
The product can also integrate with third-party solutions to determine whether the authenticating device is on an active phone call, a prime indicator of social engineering. In pilot testing on a full month of live data, reviewing the top 1% of successful challenges would have protected an estimated $4 million in fraud for one major pilot issuer in a month, at a cost of 0.38 points off its authentication success rate.
“Financial institutions are experiencing broad increases in fraud attempts driven by sophisticated, AI-enhanced social engineering attacks,” said Matt Cooke, vice president and general manager, Payment Security Division, Broadcom. Cooke also said, “Arcot Scam Defense closes a critical gap.”
Broadcom expects to add new signals, including cardholder and device attributes, and a dedicated challenge history profiling engine that learns each cardholder's past challenge behavior.
