About

The organization admin role controls organization settings, integrations, membership, and security configuration in Anthropic Claude for Enterprise. Membership role changes are reported as `claude_user_role_updated` with `anthropic.audit.current_role`. An attacker can promote a compromised or newly invited account to org admin to turn initial access into durable control-plane access. From admin, they can disable SSO, mint admin API keys for automation, start data exports, and weaken audit logging. Workspace-scoped `role_assignment_granted` grants (for example bare `admin` on a workspace) are out of scope for this rule.

False Positive Examples

IT administrators promote users to organization admin during onboarding, staffing changes, or incident response. Verify that the target user should hold org admin privileges, and that a change request exists when policy requires one.
