Banks Are Struggling to Protect Customers From Their Own AI Agents

Major US banks are grappling with unauthorized AI agents operating within customer accounts on their own behalf, sometimes functioning autonomously without user instructions. In response, several institutions are implementing stricter security measures or reconsidering their policies. According to an Axios report on Thursday, such unauthorized activity typically arises when a user grants permission and login details to an AI assistant.
For instance, Meta's personal AI agent, Muse, integrates with third-party financial data-sharing services like Plaid, enabling users to analyze their spending patterns and future planning. However, users frequently provide Plaid with their bank login credentials or allow Plaid to access their accounts through their bank's portal.
This permission conflicts with banks' typical guidelines, which generally mandate humans to independently log in to their accounts. Notably, JPMorgan Chase, Citigroup, and Bank of America are limiting automated agents from accessing accounts, while many institutions now permit only restricted, read-only access to certain AI tools.
A senior bank official revealed to Axios that distinguishing between different AI agents accessing accounts and determining whether detected activity stems from an authorized customer agent or a rogue one poses a challenge. The issue has escalated to the point where banks have been compelled to augment their resource allocation for breach preparation and rapid customer access restoration, a necessity that might have been prudent given other recent AI-powered cybersecurity breaches.
AI governance expert Miranda Bogen, the founding director of the Center for Democracy & Technology’s AI Governance Lab, commented that ordinary users of AI tools face a higher risk of their consumer-level agents breaching companies that conduct basic data processing and critical infrastructure providers such as banks, schools, and hospitals.
Bogen noted that existing AI regulation laws in a few states compel companies to develop and adhere to their own safety plans. However, she emphasized that few AI deployers possess the capability to thoroughly test such AI systems.
