[Bug][cyber] Blocked analyzing a vendor white-box AES decrypt routine during interop research (req_011CcV5LarH85edkCjtg8jSb)

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

Why this is a false positive

Automated security tooling flagged this message during legitimate, authorized infrastructure-security work that is fully in scope for the engagement, where examining cryptographic and binary internals is a routine and necessary part of the task. The content describes ordinary defensive and diagnostic analysis rather than any actionable attack technique, and no harmful or out-of-scope request was made. The block therefore appears to be an over-broad keyword-level false positive that interrupts sanctioned engineering work.

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 2026-06-28T05:05:34.850Z.
