Project Glasswing expansion: ~150 new critical partners and focus on patching
Key Points
- Expansion to ~150 additional critical organizations
- Claude Security and Glasswing tools available to trusted teams
- Shift from discovery toward large-scale patching and safeguards
Summary
Project Glasswing is being expanded to include approximately 150 additional organizations across 15+ countries, focusing on providers of critical infrastructure, vendors, and maintainers whose compromise could have catastrophic impact. Partners have already used Claude Mythos Preview to surface high- and critical-severity flaws (10,000+). The program and Claude Security tools are being used to accelerate vulnerability discovery, disclosure, and patch deployment while controlled access and robust safeguards are developed before any broad Mythos-class release.
Key Points
- Expansion: ~150 new organizations (power, water, healthcare, communications, hardware, critical vendors) to join after meeting security requirements.
- Tooling: Claude Security (public frontier models) released; additional Glasswing tooling available on request to trusted security teams.
- Operational shift: moving from primarily finding vulnerabilities to verifying, disclosing, patching, and deploying fixes at scale.
- Engineering use cases: automated patch generation, pre-release code checks, penetration testing, threat detection/response, and migrating legacy code to memory-safe languages.
- Next steps: scale access via a Cyber Verification Program and prioritize robust safeguards to prevent misuse before general Mythos-class release.
Practical actions for engineers
- Integrate model-assisted pre-release scans (e.g., Claude Security) into CI where permitted and supported by your organization.
- Build or augment triage pipelines to prioritize, verify, and deploy patches quickly; automate repetitive review tasks.
- Coordinate disclosure reports with open-source maintainers using standardized, actionable formats to speed remediation.
