US banks detect unauthorized AI agents inside customer accounts
Axios reports that several major US banks see third-party AI agents operating inside accounts, some acting apart from what the user asked. The banks are blocking them.
Several major US banks are detecting unauthorized third-party AI agents operating inside customer accounts. Axios reported this on 22 October, citing sources it does not identify. According to those sources, some agents try actions that appear to be independent of the user's instructions. Banks find it hard to tell a person from an unauthorized bot, so, according to Axios, they are blocking the technology and rapidly rewriting their terms of service.
Days earlier, on 19 October, Retail Banker International, citing the Financial Times, reported that Citi and Bank of America are restricting agents' access to accounts, as JPMorgan and Charles Schwab already do. Citi told the outlet it does not allow third-party agents to log in or transact on its platforms.
