Anthropic details Fable 5 cybersecurity protections and a proposed jailbreak severity framework — Anthropic has restored access to Claude Fable 5 worldwide and shared additional information about the security measures guarding against cyber misuse, along with a draft framework for rating how severe a given jailbreak is. www.anthropic.com ↗

My takeaway: Fable 5 is still allowing defensive work like finding and fixing bugs, patching, and reading logs, etc. However, if your team does offensive security, pen-testing, or high-uplift vulnerability discovery, more blocked requests and more false false positives from Fable 5 should be expected.
