Ex-DOGE Cybersecurity Startup Penetrates Anthropic's Internal Systems in Under 12 Hours

Cathedral, a months-old startup founded by former government officials, demonstrated how quickly AI-powered agents can discover and exploit security flaws by gaining access to Anthropic's internal business systems in less than 12 hours. The cybersecurity firm, which includes Gavin Kliger, the Pentagon's former chief data officer, reached sensitive employee data including meeting transcripts, salary information, job offers, and internal Slack discussions about Anthropic's advanced AI models—all through vulnerabilities in third-party administrative and sales software rather than Anthropic's own code.
