The email, obtained via access-to-information request, warns that Mythos is highly capable at finding and exploiting software vulnerabilities, threatening the traditional patching cycle that banks rely on. The warning follows similar meetings between US Treasury and Fed officials with bank executives, and has since been echoed by the ECB, Bank of England, and Australia's ASIC. OSFI maintains it regulates institutions rather than models, yet named the specific technology twice. Canadian banks including RBC, TD, and BMO are building AI-based defences in response. Prime Minister Carney has compared over-reliance on a few frontier AI models to the concentration risk preceding the 2008 financial crisis. ## Full article daily.dev links to this article rather than hosting it.
