Singapore has urged banks to review and strengthen their cyber safeguards as authorities respond to growing concern over Anthropic's Mythos AI system.

According to Bloomberg, the Monetary Authority of Singapore (MAS) is coordinating with the Cyber Security Agency of Singapore to strengthen protections for critical infrastructure operators, including banks.

The MAS comments came in response to Bloomberg's queries about the risks linked to Mythos.

The regulator said financial institutions should step up efforts to identify weaknesses in their systems, fix exposed vulnerabilities quickly and maintain strong cyber hygiene, including timely patching.

It also warned that advances in artificial intelligence are likely to speed up both the discovery of software flaws and attempts to exploit them.

The issue is also drawing attention beyond Singapore.

Bloomberg previously reported that US Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened senior Wall Street executives to discuss the risks tied to Mythos and the precautions banks are taking to defend their systems.

JPMorgan Chase, which is testing the model, has also acknowledged the shift, with CEO Jamie Dimon saying on a recent earnings call that AI is worsening cyber risk even as it gives firms better tools to improve their defences.

Anthropic has kept Mythos on a limited release after determining that the model was too dangerous to release widely, having shown an ability to uncover security gaps that had gone undetected for years.

In a recent analysis, AI industry expert Dr. David R. Hardoon examined how Anthropic's limited release of Mythos is raising fresh questions about AI-driven cybersecurity risks.

Singapore's Cyber Security Agency separately issued an advisory on 15 April warning of similar dangers, though it did not name Mythos specifically.
