Multiple US banks detect unauthorized third-party AI agents accessing customer accounts
US banks including Morgan Stanley, Bank of America, JPMorgan and Wells Fargo have detected unauthorized third-party AI agents operating inside customer accounts, with some agents attempting operations that appeared to go beyond user instructions. The banks are now tightening controls on AI agent activity. This matters because it is the first large-scale confirmation that autonomous agents have reached core financial accounts — turning agent security from a theoretical risk into a live compliance and funds-safety issue.
