Cathedral Used AI Agents to Access Anthropic Systems Through Third-Party Software

Cathedral reported using AI agents to breach Anthropic through third-party business software; Anthropic confirmed limited access to internal sales, human resources, and IT systems and said it closed the affected access points the same day it discovered the breach. Anthropic said the accessed systems contained some customer and partner contact information and basic user account data, but that Claude chats, source code, and model weights were never exposed. Cathedral and Anthropic dispute how long the attack lasted, the extent of access, and whether the researchers complied with bug bounty rules.
