AI-Powered Fraud Is Rising: How Banks Can Protect Customers From Deepfakes

Artificial intelligence is transforming how consumers shop, make payments and interact with financial institutions, but the rise of autonomous AI agents is creating new cybersecurity challenges. On Market Movers, Johny Fernandez speaks with Matt Thompson, CEO of Transmit Security, about the growing importance of digital identity, the risks associated with AI-powered financial transactions and how banks can protect customers while embracing the future of agentic commerce.

Thompson examines why major financial institutions, including JPMorgan Chase, Citigroup and Bank of America, are taking a cautious approach to allowing AI agents to access customer accounts. As autonomous systems become capable of initiating payments and managing financial activities, he explains why banks need to distinguish between trusted AI agents and potentially malicious software. Rather than blocking all automated activity, Thompson highlights the importance of establishing secure authorization frameworks that allow legitimate transactions while protecting sensitive financial information.

The conversation also explores the growing threat of AI-driven financial fraud. Drawing on his experience as former President of Socure, Thompson discusses the rapid increase in deepfake attacks, synthetic identities and sophisticated impersonation techniques targeting financial institutions. With Socure reporting an 8,000% increase in deepfake activity across its customer base over a one-year period, he explains why cybersecurity providers and financial institutions must adapt their defenses to keep pace with increasingly advanced fraud tactics.

Digital identity and agent authorization are another major focus as Thompson introduces the concept of agentic trust. He explains how financial institutions can develop security systems capable of identifying AI agents, verifying their connection to legitimate customers and confirming the specific financial activities they have permission to perform. These capabilities could become essential as consumers increasingly rely on autonomous systems to make purchases, pay bills and interact with banking platforms.

Thompson also discusses why financial institutions need to rethink digital customer experiences for an era in which software agents act on behalf of human users. Drawing on his experience in identity security at Capital One and Socure, he highlights how banks can extend established authentication and fraud prevention principles to AI-driven interactions. This approach involves recognizing agent activity, enforcing customer permissions and introducing additional safeguards for transactions that carry greater financial risk.
