US banks are rushing to fix scores of IT system weaknesses flagged by Anthropic's powerful but costly Mythos AI tool, prompting urgent repairs, software upgrades and raising the possibility of disruption for customers.
A handful of the country's largest lenders currently have access to Mythos, Reuters has previously reported, and are now uncovering issues the program is revealing, several sources familiar with the matter said. As they comb through the vulnerabilities, the larger banks are also helping inform smaller banks who do not have direct access to the tool so they can prepare their systems, those sources said. Mythos is viewed by cybersecurity experts as posing significant challenges to the banking industry and its legacy technology systems, prompting a series of warnings from regulators and policymakers.
