According to multiple outlets, banks such as Morgan Stanley, JPMorgan, Bank of America, and Citi are implementing restrictions on these AI tools to protect customer data and financial security.
The unauthorized AI agents, often referred to as 'rogue bots,' have raised significant concerns among financial institutions.
