Unvetted AI Agents Are Accessing US Bank Accounts
An anonymous reader quotes a report from Axios: Major U.S. banks are detecting unauthorized third-party AI agents operating inside customer accounts, with some agents attempting to take actions that appear to be independent of user instructions, sources tell Axios. The difficulty in distinguishing between a human and an unauthorized bot is forcing banks to block the technology and rapidly rewrite their terms of service. […] 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. In other instances, some banks have tracked activity when agents — programmed to fulfill requests or complete tasks on a user’s behalf — contact call centers or appear to take actions independent of user instructions, the people said.
Bank executives described the situation as horrifying, with one official saying the industry has grave concerns about agents gaining access to customer accounts and taking steps that could impact user finances. The concerns are at the root of the decision by several banks to restrict third-party AI agent access, the people said. Morgan Stanley has begun blocking third-party agents from accessing its platforms, sources familiar with the decision said. JPMorgan, Bank of America and Citi are also restricting agents. […] Many banks are broadly not able to parse whether agent account activity is user-directed, sources said.
[…] On one hand, banks are best positioned to respond to the threats and opportunities of AI given their cash on hand and experience as critical infrastructure. But money isn’t necessarily enough to solve this problem, one source said, because of how quickly the technology is developing and revealing new weaknesses in real time. Banks are investing in preventing worst-case scenarios, but they are also preparing for when those could happen, including with “day after” scenario planning that would allow them to quickly secure or restore customer access, sources said.
