Cybersecurity experts say Mythos, an AI model described as extremely capable at finding and exploiting cybersecurity vulnerabilities, poses significant challenges to the banking industry and its legacy technology systems.  <\/p>\n<p class=\"text text-block paragraph text-left neo-font-paragraph-xl-reg  yf-18d6y07\" style=\"text-decoration: none; font-style: normal; text-transform: none; text-align: inherit; font-variant-numeric: normal;\">&#8220;Advanced artificial intelligence models, such as Anthropic Claude Mythos, significantly compress the timeframe for effective risk mitigation,&#8221; OSFI said in the email.  <\/p>\n<p class=\"text text-block paragraph text-left neo-font-paragraph-xl-reg  yf-18d6y07\" style=\"text-decoration: none; font-style: normal; text-transform: none; text-align: inherit; font-variant-numeric: normal;\">&#8220;Accordingly, this bulletin is grounded in our existing guidance and outlines sound practices that institutions can adopt to enhance the \u200cspeed and effectiveness of risk identification, mitigation and response.&#8221;  <\/p>\n<p class=\"text text-block paragraph text-left neo-font-paragraph-xl-reg  yf-18d6y07\" style=\"text-decoration: none; font-style: normal; text-transform: none; text-align: inherit; font-variant-numeric: normal;\">Additional \u2060contents of the email were redacted due to some sections of the Access to Information Act.

A judge blocked its initial blacklisting by the Pentagon in March, and the conflict \u200chas eased following the private release of Anthropic&#8217;s Mythos.  <\/p>\n<p class=\"text text-block paragraph text-left neo-font-paragraph-xl-reg  yf-18d6y07\" style=\"text-decoration: none; font-style: normal; text-transform: none; text-align: inherit; font-variant-numeric: normal;\">Three of Canada&#8217;s big six banks &#8211; Royal \u200bBank of Canada, TD Bank and BMO &#8211; have outlined a plan to earn millions from their investments \u200bin AI as the banks moved from experimental AI projects to applying \u200bthem in chatbots, building internal tools and lowering their reliance on third-party tools.  <\/p>\n<p class=\"text text-block paragraph text-left neo-font-paragraph-xl-reg  yf-18d6y07\" style=\"text-decoration: none; font-style: normal; text-transform: none; text-align: inherit; font-variant-numeric: normal;\">Bank of Nova Scotia, CIBC and National Bank have also \u200cdisclosed several AI initiatives.  <\/p>\n<p class=\"text text-block paragraph text-left neo-font-paragraph-xl-reg  yf-18d6y07\" style=\"text-decoration: none; font-style: normal; text-transform: none; text-align: inherit; font-variant-numeric: normal;\">The Canadian government has said it has access \u200bto Anthropic&#8217;s Project Glasswing, which allows companies \u200bto have access to Mythos. It is not clear which, if any, banks in Canada are using it.
