Summary

On May 4, 2026, euro-area finance ministers convened in Brussels to address the lack of access to Anthropic's Mythos AI model, which can autonomously identify and exploit zero-day vulnerabilities across major operating systems and browsers. The model, unveiled on April 7, 2026, is currently restricted to American tech companies and the NSA under Project Glasswing. No European government or bank has access, raising concerns about the security of Europe’s financial infrastructure. The Bundesbank has urged the EU to demand access, citing that without it, European banks cannot adequately defend against potential AI-powered cyberattacks. The model has demonstrated the ability to discover critical vulnerabilities, including CVE-2026-4747, which allows complete control over targeted servers. The situation highlights the limitations of Europe’s AI Act, which lacks mechanisms to compel access to such powerful technologies. The White House's ongoing blockage of access expansion exacerbates the issue, leaving European entities vulnerable to advanced cyber threats. Key Points: • Anthropic's Mythos AI can autonomously find zero-day vulnerabilities in major systems. • No European government or bank currently has access, limiting their defensive capabilities. • The EU's AI Act does not provide mechanisms to compel access to critical AI technologies.
