Expanding Project Glasswing

Summary

Project Glasswing is expanding its collaboration from roughly 50 initial partners to approximately 150 new organizations across more than 15 countries. These partners must meet security requirements, and many operate critical infrastructure or maintain software used widely, with a major attack estimated to affect more than 100 million people for most. The program follows partners’ use of Claude Mythos Preview to scan codebases, finding more than 10,000 high- or critical-severity flaws, while some now use it to write patches and run pre-release checks. Its broader purpose is to help defenders adapt to powerful cyber models by providing tools and infrastructure, then shifting support toward disclosure, fixing, and deployment of patched software. General access will require safeguards against misuse that have yet to be developed.

Takeaways

1. 1

   Roughly 50 initial partners used Claude Mythos Preview to scan codebases and have found more than 10,000 high- or critical-severity security flaws.

2. 2

   The new cohort spans more than 15 countries and includes power, water, healthcare, communications, and hardware organizations, as well as software vendors and nonprofits.

3. 3

   The program identifies verifying, disclosing, and patching the volume of vulnerabilities surfaced by Mythos-class models as a current cybersecurity bottleneck.
