The ECB is demanding that Europe’s 110 directly supervised banks develop action plans by late October to address AI-driven cybersecurity risks, focusing on faster vulnerability patching, AI-enabled monitoring, and tighter oversight of third-party providers.

Regulators warn that widespread cyber disruptions could erode public confidence, potentially triggering runs on banks or even national economies with weak cyber resilience.

Frontier AI models are seen as a systemic threat to the financial sector, enabling faster, more sophisticated cyberattacks and raising the risk of a broad financial disruption.

Anthropic has released Mythos publicly with safety safeguards after initially withholding the full model due to misuse concerns.

Anthropic expanded access to Claude Mythos Preview to about 150 new organizations across more than 15 countries, extending its Project Glasswing collaboration with various partners including US authorities.

Longer-term priorities call for strengthening defense in depth, cyber hygiene, and modernization of infrastructure to boost operational and cyber resilience.

Industry guidance suggests prioritizing security vendors like Thales and Sopra Steria for cybersecurity spend and Atos or Capgemini for payment resilience and systems integration, aligned with the four‑month push.

Industry chatter references frontier models like Mythos as highly capable AIs with strong cyber capabilities, though official warnings do not name specific models.

Mythos is cited as an example of frontier AI that can identify software weaknesses, underscoring the need for enhanced defenses and monitoring.

Banks are urged to focus on systems integration, incident-response tooling, and modernization, benefiting large IT service providers through increased demand.

Authorities stress immediate remediation of deficiencies found during inspections and stress tests to protect operational resilience.

FAIMs are described as capable of discovering vulnerabilities, generating exploits, and autonomously executing full-scale cyberattacks at unprecedented speed, signaling a paradigm shift in cybersecurity.
