3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
An AI startup called Cathedral, founded by former DOGE members, says it used autonomous agents to breach Anthropic's systems through flaws in third-party business software, reaching limited HR, sales, and IT data after human researchers failed for days.
Why it ranked
No. 74 of 127 with a score of 0.61. The panel rated it highest on reader interest (0.81) and audience breadth (0.74), lowest on technical depth (0.38). The judges disagreed most on new information (spread 0.63), so the story is marked contested. Placed No. 74, No. 63 by score alone: the 30th Security story of the day (−0.080). The placement terms move stories; they are not part of the score.
- AI judgeJudge 2claude-haiku-5-5
- Security incident involving AI agents breaching a major AI lab via third-party vendor weaknesses; newsworthy and practical for security-minded builders, but a secondhand news report with thin technical detail.
- AI judgeJudge 3gpt-5.6-luna
- A timely security incident involving autonomous AI agents, third-party enterprise software, and Anthropic is highly relevant. The report provides meaningful facts but limited technical detail and relies mainly on secondary reporting and quoted statements.
