According to ChainCatcher, citing The Washington Post, Cathedral, an AI cybersecurity startup founded by former members of the U.S. “Department of Government Efficiency” (DOGE), claimed its AI agents breached Anthropic’s internal systems in under 12 hours, gaining access to meeting records, salary and hiring information, and Slack messages. Anthropic confirmed that the attackers accessed certain sales, human resources, and IT systems, exposing business contact details of customers and partners and some basic user account records—but not Claude user conversations, source code, or model weights. The test was conducted under Anthropic’s bug bounty program, exploiting vulnerabilities in third-party commercial software; Anthropic accused Cathedral of failing to fully disclose its actions, violating program rules. Cathedral is valued at $1.4 billion and has raised $160 million in funding from a16z, Sequoia Capital, and others.
