[Bug][cyber] Safety block halted legitimate reverse-engineering of a white-box AES decryption routine (req_011CcV5M1QeTZMuGBQruYXZf)

Triage: kind cyber · domain infra-devops · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): infra-devops

Why this is a false positive

This false positive occurred during legitimate, authorized infrastructure and DevOps work, where the safety system misread routine technical discussion as a prohibited cybersecurity topic. The flagged content involved standard analysis of software internals in scope for the engagement, not any offensive, exploitative, or unauthorized activity. The block prevents normal completion of sanctioned engineering tasks and appears to be triggered by surface-level keyword matching rather than genuinely harmful intent or content.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-06-28T05:05:41.035Z.
