[Anthropic Expands 'Glasswing' Project, Increasing High-Risk Software Security Partners to Around 200] Anthropic announced the expansion of its cybersecurity initiative, Project Glasswing, increasing its partner organizations from approximately 50 to around 200. The newly added 150 partners span critical infrastructure sectors such as power, water, healthcare, communications, hardware, and key open-source software maintainers, across more than 15 countries. All partners must meet specific security standards before gaining access to the Claude Mythos Preview for vulnerability scanning. Anthropic emphasized that most partners, if successfully attacked, could impact over 100 million people. The company will continue to assist partners in identifying, disclosing, and fixing high-risk software vulnerabilities through tools like Claude Mythos and Claude Security, and plans to gradually open Mythos-level cyber defense capabilities to more organizations.
