Cathedral, an AI-driven cybersecurity firm led by former Department of Government Efficiency members, publicly disclosed that it penetrated Anthropic's internal infrastructure including meeting transcripts, salary data, and Slack messages. The firm claims the breach occurred in under 12 hours through weaknesses in standard business software used across many organizations. The incident qualifies as authorized security testing under Anthropic's bug-bounty-like program. Anthropic acknowledged the limited access and remediated the vulnerabilities.
