Major US Banks Report Unauthorized AI Agents in Customer Accounts, Restrict Access

Major U.S. banks, including JPMorgan Chase, Bank of America, Morgan Stanley, Wells Fargo and Citigroup, have found unauthorized AI agents operating inside customer accounts, according to an Axios report published Thursday. Some agents appeared to take actions their users had not instructed, and banks said they have seen agents contacting call centers. A bank official told Axios that banks struggle to tell agents apart, or to know whether an agent was authorized by a customer or has gone rogue. Morgan Stanley has begun blocking third-party agents, while JPMorgan, Bank of America and Citi are restricting agent access. Many banks are allowing or moving toward read-only access, which lets agents view account information. Banks are also investing more in breach preparedness and in restoring customer access quickly. A Morgan Stanley spokesperson denied reports of rogue AI agents accessing its platforms.

Left-leaning coverage (Mother Jones) cites the Financial Times and Axios and places the story within other AI-related cybersecurity breaches, quoting a technology policy expert. Alternative coverage (ZeroHedge) relies on Axios and stresses what agents could do, such as purchases or transfers, and executives' worries about oversight. Right-leaning coverage (Breitbart) leads with bank officials' strong language, including "horrifying," and includes Morgan Stanley's pushback. All three agree on the core facts: unauthorized agents, difficulty identifying them, and restricted access.
