Banks including Morgan Stanley, Bank of America, JPMorgan, Wells Fargo and others are racing to contain agent risks. Some are aware of unauthorized access, people familiar with the issue said. These are generally situations when an agent or AI assistant accesses a human's account with the user's permission and login credentials. Even if permitted by the user, this goes against the guidelines of most banks requiring that humans log in to their own accounts. This presents significant security risks: Banking executives fear the steps agents with login access might take, especially if a user has granted purchase authority or the ability to shift funds.
