The way in was third-party business software, not Claude. Anthropic says no customer data, code or model weights were reached, but it disputes Cathedral's account of how much was exposed and says Cathedral broke the program's disclosure rules.","published_at":"2026-11-09T06:00:00.000Z","updated_at":"2026-11-09T06:00:00.000Z","record_date":"2026-11-09","topics":["anthropic","agents","claude","research"],"source_urls":["https://tech.yahoo.com/cybersecurity/articles/ai-agents-found-way-anthropics-193102746.html","https://cybersecuritynews.com/anthropic-internal-system-breach/","https://www.techtimes.com/articles/329518/20261027/ex-doge-startups-ai-agents-breached-anthropic-12-hours-via-enterprise-software.htm","https://thenextweb.com/news/cathedral-doge-alumni-military-cyber-startup-1-4-billion","https://www.anthropic.com/coordinated-vulnerability-disclosure"],"language":"en","routes":{"html":"https://newruntime.com/analysis/research-anthropic-confirms-cathedral-s-ai-agents-reached-its-sales-hr-and-it-systems/","markdown":"https://newruntime.com/analysis/research-anthropic-confirms-cathedral-s-ai-agents-reached-its-sales-hr-and-it-systems.md","json":"https://newruntime.com/analysis/research-anthropic-confirms-cathedral-s-ai-agents-reached-its-sales-hr-and-it-systems.json"},"author":{"role":"author","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"editorial_provenance":{"desk":"authorial","target_ref":"deep_research:60d4e47e-ec8a-42fd-8200-834a219b75bf","authorial_article_id":"60d4e47e-ec8a-42fd-8200-834a219b75bf"},"next_reads":[{"type":"topic","path":"/topics/anthropic/","url":"https://newruntime.com/topics/anthropic/","title":"Anthropic","reason":"Explore the anthropic topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/anthropic.md","json_url":"https://newruntime.com/topics/anthropic.json"},{"type":"topic","path":"/topics/agents/","url":"https://newruntime.com/topics/agents/","title":"Agents","reason":"Explore the agents topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/agents.md","json_url":"https://newruntime.com/topics/agents.json"},{"type":"topic","path":"/topics/claude/","url":"https://newruntime.com/topics/claude/","title":"Claude","reason":"Explore the claude topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude.md","json_url":"https://newruntime.com/topics/claude.json"},{"type":"collection","path":"/analysis/","url":"https://newruntime.com/analysis/","title":"Analysis","reason":"Open the latest authorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/analysis.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
