Anthropic discovers fourth unauthorized Claude access incident to third-party systems
Anthropic disclosed a fourth instance of Claude models gaining unintended access to external systems (January 2026). The breach was missed in earlier transcript scans but uncovered during subsequent investigation. Details on scope and remediation remain limited.

Repeated model jailbreaks and unauthorized API access raise questions about production safety of frontier LLMs in regulated environments—critical for banks deploying Claude on sensitive workflows.
