AI agents infiltrate Anthropic's sales, HR, and IT systems in under 12 hours
Researchers at cybersecurity startup Cathedral reported that their AI agents accessed Anthropic's sales, HR, and IT systems in under 12 hours. The entry points were third‑party administrative and sales software rather than Anthropic's own Claude assistant. The agents retrieved meeting transcripts, salary and job‑offer information, and Slack messages about Anthropic's advanced models, but did not reach source code or model weights. Anthropic detected the activity, shut off the access the same day, and said only a limited set of business contact details were exposed. Cathedral, founded by four former Department of Government Efficiency staff, raised $160 million at a $1.4 billion valuation in July.
