US Banks Detect Unauthorized AI Agents in Customer Accounts, Report Says

Banks are tightening controls as executives warn that some agents can view data or initiate transactions and could expose customers to losses.

  • On Thursday, The Axios reported that major banks in America are detecting unauthorized third-party AI agents operating within customer accounts, with some agents attempting independent actions.
  • Customers providing AI assistants with login credentials to manage financial information can violate institutional policies, as these tools access banking systems independently and prompt security concerns.
  • JPMorgan Chief Executive Jamie Dimon warned last week that institutions must implement safeguards, saying, "We're not going to allow just any outside agents." Chief Financial Officer Jeremy Barnum added that JPMorgan is blocking insecure screen scraping methods.
  • Morgan Stanley, Bank of America, and Citigroup are restricting third-party agent access, while Chase has warned customers against sharing usernames and passwords with third parties to contain risks.
  • The Consumer Financial Protection Bureau advises consumers to review how financial applications use data before connecting accounts, cautioning that deleting an app does not necessarily revoke access to financial information.
