Singapore's Monetary Authority (MAS) has issued a stark warning to banks and financial institutions, urging immediate cybersecurity upgrades. The alert follows concerns over Anthropic's unreleased Mythos AI model, which the developer deemed too dangerous for public release. This intervention underscores growing regulatory unease about AI's potential to destabilize both traditional finance and decentralized systems.

The advisory specifically targets cryptocurrency exchanges, custodians, and DeFi protocols operating in Singapore's thriving Web3 ecosystem. With banks serving as critical fiat on-ramps and digital asset custodians, the MAS emphasizes cascading risks across payment networks and blockchain infrastructures. 'When AI systems interact with financial architectures at scale,' observed one fintech executive, 'we're navigating uncharted threat vectors.'
