Anthropic Gives EU Cybersecurity Agency Access to Powerful AI Hacking Model
Anthropic granted ENISA access to Claude Mythos, marking the first non-US/UK entry into Project Glasswing.
"A government cybersecurity agency now has access to an AI that finds zero-days at industrial scale. The patching era just got a hard deadline."
Anthropic PBC has extended access to Claude Mythos — its restricted, high-capability cybersecurity AI — to the European Union Agency for Cybersecurity (ENISA), making it the first EU body admitted to Project Glasswing. The decision was communicated to the European Commission over the weekend of May 31–June 1, 2026, and represents the first time Anthropic has granted Mythos access outside the United States and United Kingdom.
Launched in April 2026, Claude Mythos autonomously identifies security flaws in complex codebases and generates working exploits on the first attempt in over 83% of cases. The model has already flagged more than 10,000 zero-day vulnerabilities, including a 27-year-old flaw in OpenBSD and a 17-year-old vulnerability in FreeBSD. Project Glasswing counts over forty organizations — including Amazon, Apple, Microsoft, Google, and the Linux Foundation — with Anthropic committing $100 million in usage credits and $4 million in direct donations to open-source security groups.
The ENISA partnership signals a calculated geopolitical move by Anthropic as it approaches a near-trillion-dollar valuation of $965 billion, with $47 billion in run-rate revenue and projected 130% growth. Bringing a sovereign EU regulatory body into Glasswing could ease forthcoming AI Act compliance pressures while positioning Mythos as the default infrastructure-security standard across Europe.
Enterprises operating under EU jurisdiction may soon interact with AI-driven vulnerability detection tools endorsed or deployed by ENISA, raising the bar for compliance and vendor security expectations. For executives, this signals that AI-powered offensive security is moving from research labs into regulatory frameworks. Business owners relying on open-source software stacks should monitor Glasswing disclosures closely — coordinated zero-day patches may accelerate significantly.
