WASHINGTON—Fresh warnings from regulators and bank executives across the Asia-Pacific region are reinforcing what may be the clearest message yet for U.S. financial institutions: Anthropic’s Claude Mythos is rapidly moving from experimental cybersecurity tool to a potentially major new source of cyber risk, with concerns now escalating from supervisory circles to the White House.
Reuters reported that Australia’s prudential regulator, APRA, warned banks they are falling behind on frontier-AI cyber risk, specifically cautioning that systems such as Anthropic’s Claude Mythos could help malicious actors identify and exploit vulnerabilities faster and at greater scale. APRA said many institutions are not keeping pace with the speed of AI development, citing weak board-level technical literacy and too much reliance on vendor summaries rather than deeper internal risk assessments.

Reuters also reported that banks across Asia said they are bracing for more complex cyber threats as Anthropic’s Claude Mythos Preview under Project Glasswing spreads through the market. Reuters said major institutions in Singapore and elsewhere are reassessing AI deployment protocols, while executives at banks including DBS, OCBC, UOB and Standard Chartered acknowledged the model could materially increase the speed and sophistication of attacks even as they continue to see defensive value in the technology.
The broader backdrop has only intensified. Reuters has previously reported that European supervisors are probing banks on Mythos preparedness, central banks in Australia and New Zealand are monitoring the model, and large institutions have been scrambling for access as regulators try to gauge whether firms are ready for what could be a step-change in cyber offense and defense. Reuters also reported earlier this month that Anthropic’s Mythos could “supercharge” complex cyberattacks and that the White House and Anthropic were trying to reset relations after a dispute over the model’s rollout.
Separately, The Wall Street Journal reported that the White House opposed Anthropic’s plan to broaden access to Mythos on national-security grounds, adding a political and national security layer to what had already become a major operational risk story for financial institutions.
