Anthropic Scales Claude Mythos to Critical Infrastructure in 15+ Countries

Anthropic is significantly expanding Project Glasswing, its AI-powered security vulnerability program, to approximately 150 organizations across more than 15 countries. This expansion targets critical infrastructure sectors where cyberattacks could affect over 100 million people.

What is Claude Mythos?

Claude Mythos is Anthropic's most powerful AI model designed specifically for cybersecurity. The model can identify thousands of zero-day vulnerabilities over several weeks by scanning codebases for security flaws.

Key Details of the Expansion

Target Sectors

  • Power and energy systems
  • Water infrastructure
  • Healthcare organizations
  • Communications networks
  • Hardware manufacturers

Geographic Reach

The expansion includes organizations in U.S.-allied countries:

  • Australia
  • Canada
  • France
  • Germany
  • Italy
  • Switzerland
  • Netherlands
  • Spain
  • Belgium
  • Sweden
  • India
  • Japan
  • New Zealand
  • South Korea

Confirmed Partners (per Financial Times reporting)

  • Okta (U.S. identity and security management)
  • Samsung (South Korea)
  • SK Hynix (South Korea)
  • SK Telecom (South Korea)
  • NATO (U.S.-led military alliance)
  • ENISA (EU cybersecurity agency)

Project Glasswing Timeline

April 2026: Anthropic launched Project Glasswing with 50 initial partners, including the U.S. government, giving them access to Claude Mythos Preview.

June 2026: Expansion to 150 organizations across 15+ countries, focusing on critical infrastructure not well-represented in the initial cohort.

Competitive Landscape

Anthropic acknowledges that other AI companies will soon develop models as capable as Mythos, which is why the company is racing to establish safeguards. Rival OpenAI has already released GPT-5.5-Cyber, a competing cybersecurity-focused model being tested with a large partner group.

Strategic Context

This announcement comes one day after Anthropic filed confidentially for an IPO following a $65 billion funding round at nearly a $1 trillion valuation.

Why This Matters

According to Anthropic, each partner organization maintains codebases that other organizations and governments rely upon. A successful attack on these systems could be catastrophic, affecting more than 100 million people and having major implications for global and national security.
