Cathedral AI Agents Breach Anthropic via Third‑Party Software
Cybersecurity startup Cathedral used AI agents to infiltrate Anthropic’s internal systems through third‑party business software, accessing sales, HR, and IT data during a bug‑bounty program. Anthropic confirmed some data exposure but disputes the depth of the breach, and Cathedral says the incident took less than twelve hours.
Why it matters
Product managers of AI platforms should audit third‑party integrations for credential exposure, as breaches can occur within hours.
