At a glance: The EU gains access to Anthropic’s Mythos model after weeks of restriction, but must first implement internal security measures for technical integration.
Anthropic has formally granted the European Commission and the cybersecurity agency ENISA access to its security model Mythos. This ends a multi-week exclusion of European authorities from analyzing the AI hacking tool.
The access offer follows a meeting between representatives of the European Commission and the leadership of Anthropic in San Francisco. Commission spokesperson Thomas Regnier confirmed several productive rounds of discussion and welcomed the “recent progress.” Before EU authorities can practically work with Mythos, however, the Union must first implement internal mechanisms and security measures to secure system interaction.
The Mythos model was publicly introduced by Anthropic in April 2026 and triggered international security concerns. Unlike standard language models, Mythos is highly specialized in the automated identification and exploitation of software vulnerabilities: the system can autonomously search source code for logical errors and generate functioning exploits. This capability for large-scale automation of cyberattacks resulted in European authorities and analysts being excluded from use for several weeks. European politicians subsequently demanded equal footing in analyzing offensive AI tools to adapt national defense strategies.
The European Commission is currently working on a formal action plan against offensive artificial intelligence. This strategic document is intended to define regulatory and operational responses to the rapid market development of powerful AI hacking tools. According to industry insiders, the Commission plans to publish it before the parliamentary summer recess in 2026. Regnier emphasized in an official statement: “This recent development is of paramount importance in obtaining a clear picture of the potential risks. Let us not forget that Mythos is not an isolated case; a new wave of powerful models is coming to the market.”
The cybersecurity agency ENISA currently does not have active access but is intensively working on the organizational prerequisites for technical integration. The multi-week exclusion of European security authorities has triggered a fundamental debate in Brussels about the EU’s technological dependence on US artificial intelligence monopolies. The access that has now been granted is evaluated by political observers as a partial success in closing information gaps, but also underscores the need for independent European testing environments and stronger digital sovereignty.
