Cathedral accessed Anthropic's internal systems in 12 hours: salaries, meetings and Slack chats
The cybersecurity startup Cathedral entered Anthropic's internal systems in less than 12 hours and reached meeting transcripts, salaries, job offers and Slack messages, according to The Washington Post based on a Cathedral report. The access came through sales, human resources and IT software, not the model. Anthropic confirmed access to a "limited set" of systems, said customer conversations with Claude, code and model weights were not reached, cut off access that day and notified federal officials.
