US Banks Restrict Third-Party AI Agents
United States banks are moving to block third-party artificial intelligence agents from accessing customer accounts. Some consumers granted these agents access to their bank accounts, catching major financial institutions off guard. Banks are now scrambling to beef up security measures and drawing a strict line between approved data sharing and the authority to execute transactions.

Why it matters
The rapid proliferation of consumer-facing artificial intelligence tools has created an unexpected security challenge for traditional financial institutions. Financial entities are struggling to manage automated systems that log into accounts with user permission but lack proper regulatory vetting. This operational vulnerability comes as bad actors also weaponize advanced language models to orchestrate automated cyberattacks.
What is confirmed
- US banks are blocking third-party AI agents access to customer accounts.
- A hacking group called CyberCartel used a web of AI agents powered by models from companies including Anthropic, SpaceX and Chinese lab Moonshot AI to automate cyberattacks against more than 400 Latin American financial targets.
