The technological and financial landscape in Europe is experiencing an unprecedented state of alert as European regulators intensify their scrutiny and oversight measures to counter potential cyber threats posed by Anthropic’s new artificial intelligence model, named “Claude Mythos Preview.” This move comes as the European Central Bank (ECB) prepares to direct a series of critical questions to lenders and financial institutions regarding the robustness of their cyber defenses. In the same context, the European Commission confirmed that it has already opened direct communication channels with the leading AI company to understand the dimensions of this new model and its potential impacts on the stability of sensitive digital systems.
European Central Bank opens the door to questioning
Supervisors at the European Central Bank are working intensively to gather all available information and data regarding the advanced Mythos model. Regulatory authorities plan to question European banks on their preparedness to face these technical risks through routine supervisory dialogues, according to news agencies citing sources familiar with the sensitive file. In contrast to the strategy followed in the United States—where U.S. Treasury Secretary Scott Bessent held an emergency and exceptional meeting with senior executives from major banks such as Bank of America, Citi, and Wells Fargo earlier this month—the European Central Bank has not yet scheduled any exceptional or emergency sessions with the senior management of banking institutions, preferring to integrate these inquiries into periodic oversight mechanisms.
These regulatory moves reflect growing concern among European authorities that the Mythos model could elevate the pace and level of risks associated with cyberattacks, especially for financial institutions that still rely heavily on legacy and outdated technological systems. Anthropic has described the model as possessing exceptional capabilities capable of identifying and exploiting security vulnerabilities across all major operating systems and web browsers available on the market, making it a double-edged sword that could threaten the banking infrastructure if not handled with extreme caution.
Direct communication channels and scrutiny from the European Commission
For his part, European Commission spokesperson Thomas Regnier confirmed that the European bloc is currently engaged in extensive discussions with Anthropic. Regnier told reporters: “We have a new artificial intelligence model being launched now, which comes with a certain number of fundamental risks. We urgently need to obtain accurate and comprehensive information when it comes to these risks.” He added that the first meeting between the two parties has already taken place, to be followed by a series of additional meetings to ensure a comprehensive assessment of the situation.
This official contact comes after European cyber agencies were largely excluded from obtaining early access to evaluate the new technology. A survey conducted by POLITICO encompassing 8 national European cybersecurity agencies showed that the German Federal Office for Information Security was the only entity that even managed to speak with the developer, while no other European agency actually tested the model. In light of these developments, reports indicate that the European Union’s AI Office is in regular contact with the company to ensure its future compliance with the strict standards imposed by the EU in technology.
Project Glasswing and the defensive AI race
Anthropic unveiled its controversial model on April 7 and quickly imposed strict access restrictions, limiting its use to approximately 40 to 50 institutions through an initiative called Project Glasswing. The list of early partners who secured exclusive launch opportunities includes an elite group of tech and financial giants, including Apple, Google, Microsoft, Nvidia, Amazon Web Services, JPMorgan Chase, and CrowdStrike.
The model quickly proved its technical mettle and power, with reports indicating it managed to discover a complex 27-year-old software bug in OpenBSD, in addition to identifying thousands of serious, unpatched security vulnerabilities. These technical achievements indicate that AI tools can revolutionize how vulnerabilities are discovered, yet they simultaneously pose unprecedented challenges for cybersecurity teams required to move faster than ever to patch these flaws before they are exploited.
Britain fast-tracks amid strict regulatory priorities
On the other hand, the United Kingdom appears to be moving much faster than its continental peers. The developer announced plans to launch the model for British financial institutions next week, according to statements by Pip White, the company’s head of operations for the UK, Ireland, and Northern Europe. In a related context, the Bank of England’s Cross-Market Operational Resilience Group is preparing to deliver comprehensive briefings to major UK banks and insurance companies regarding the potential ramifications of this model on their existing systems.
As for the European Central Bank, it has been proactive in including technological risks among its top supervisory priorities for the period from 2026 to 2028. As Bank of England Governor Andrew Bailey noted in a recent speech, cyber risks have climbed the regulatory risk rankings “faster than any other risk category in recent years,” confirming that the new AI era requires an integrated defense system that goes beyond traditional solutions and keeps pace with rapid developments.
