The Project Glasswing partners can now pass vulnerability findings to other security teams, industry bodies, regulators, open-source maintainers and the press, under responsible-disclosure norms. The defender pool just got wider.

Anthropic said on Monday that it is revising its earlier disclosure policy on Mythos, the unreleased cybersecurity-focused AI model deployed under its Project Glasswing controlled-access programme.

The revision will let partners using Mythos share information about cyber threats with other parties potentially exposed to the same vulnerabilities, rather than holding findings within the original partner organisation.

The list of parties partners can now share with is, on the published text, deliberately broad: security teams at other companies, industry bodies, regulators and government agencies, open-source maintainers, the media and the public, all subject to responsible-disclosure norms.

Anthropic’s previous posture had been substantially tighter, with findings held inside the partner programme and surfaced upward to Anthropic itself rather than outward to the wider defender community.
