Ex-DOGE Startup’s AI Agents Breached Anthropic in 12 Hours via Enterprise Software

Cathedral, a months-old AI cybersecurity startup co-founded by four former Department of Government Efficiency (DOGE) staffers, confirmed Monday that its researchers breached sensitive internal systems at Anthropic — the maker of Claude — in under 12 hours, using AI agents to exploit vulnerabilities in third-party business software rather than Anthropic's own code. The disclosure has opened a public dispute between the two companies over scope, transparency, and the national-security implications of how frontier AI labs secure the administrative software surrounding their most sensitive assets. The entry point was not Claude, not Anthropic's model weights, and not its source code. It was the HR platforms, sales CRMs, IT management tools, and collaboration software that Anthropic — like virtually every major technology organization — relies on for ordinary business operations.
