The International Monetary Fund (IMF) has warned that AI-driven cyberattacks pose a growing threat to financial stability, potentially triggering funding strains, solvency concerns, and market disruption. The IMF cited Anthropic's release of Claude Mythos Preview as a significant example of the growing threat. The financial system relies on shared digital infrastructure, including software, cloud services, and payment networks, as well as energy, telecommunications, and public services sectors. It is essential for greater international coordination, particularly for emerging economies with weaker defenses.
