Some US banks detect unauthorized AI agents in customer accounts: Report

Major US banks including Morgan Stanley, JPMorgan, Bank of America and Wells Fargo are detecting unauthorized third-party AI agents accessing customer accounts and performing actions that may exceed user instructions, prompting institutions to tighten restrictions on automated access. Banks report difficulty distinguishing between human and automated activity, with some agents accessing accounts through customer-provided credentials in violation of bank policies or contacting customer service independently. The financial institutions are implementing controls such as read-only permissions for AI agents and reviewing terms of service to limit unauthorized transactions and financial operations.
