The company reportedly used AI agents to achieve this breach. A report detailing these findings was reviewed by The Post, which confirmed that Cathedral had communicated these results to the makers of the Claude chatbot. The startup is described as being only months old. The article does not specify the exact date of the breach or the specific AI models used, nor does it confirm whether Anthropic has verified the claims independently.","keyPoints":["Cathedral claims it breached Anthropic's internal systems in under 12 hours.","The startup was founded by ex-DOGE staffers and is months old.","AI agents were used to penetrate the sensitive systems."],"whyItMatters":"This incident highlights the potential security risks associated with AI agents in cybersecurity, suggesting that automated tools can rapidly compromise even sophisticated internal systems.","category":{"slug":"business","name":"Business & Funding","url":"https://digestai.news/category/business"},"entities":{"companies":["Cathedral","Anthropic"],"models":["Claude"],"people":[]},"firstPublishedAt":"2026-10-26T11:35:03Z","updatedAt":"2026-10-26T11:35:03Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"washingtonpost.com","title":"Cathedral, a months-old cybersecurity startup founded by ex-DOGE staffers, says it breached Anthropic's internal systems in under 12 hours using AI agents","url":"https://washingtonpost.com/technology/2026/10/26/researchers-cybersecurity-start-up-cathedral-got-inside-anthropic?pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJyZWFzb24iOiJnaWZ0IiwibmJmIjoxNzkyOTg3MjAwLCJpc3MiOiJzdWJzY3JpcHRpb25zIiwiZXhwIjoxNzk0MzczMTk5LCJpYXQiOjE3OTI5ODcyMDAsImp0aSI6ImI1M2RjZmEzLThkNTItNGE3NC05ZjI4LWU1ZGJkZTIyZDFmOSIsInVybCI6Imh0dHBzOi8vd3d3Lndhc2hpbmd0b25wb3N0LmNvbS90ZWNobm9sb2d5LzIwMjYvMTAvMjYvcmVzZWFyY2hlcnMtY3liZXJzZWN1cml0eS1zdGFydC11cC1jYXRoZWRyYWwtZ290LWluc2lkZS1hbnRocm9waWMvIn0.k3b70wv6ePisrPvCYfDOPAjt5vHweVxm4rBnhcnDU-M&itid=gfta","publishedAt":"2026-10-26T11:35:03Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Cathedral says it breached Anthropic systems in under 12 hours\", 26 October 2026, https://digestai.news/story/cathedral-says-it-breached-anthropic-systems-in-under-12-hours","publisher":"Digest AI","title":"Cathedral says it breached Anthropic systems in under 12 hours","datePublished":"2026-10-26T11:35:03Z","url":"https://digestai.news/story/cathedral-says-it-breached-anthropic-systems-in-under-12-hours"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
