[Bug][cyber] Safety block halted legitimate firmware cryptographic analysis and reverse-engineering documentat (req_011CcosqUCuVXH5KoYwsevZw)

Triage: kind cyber · domain general · flagging model Opus 4.8 · 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): general

Why this is a false positive

User was conducting authorized security research on embedded firmware, extracting and documenting static cryptographic keys via binary analysis and dynamic instrumentation to understand authentication mechanisms. The block fired mid-analysis on a technical summary of key findings and project documentation — substantive reverse-engineering work that falls squarely within authorized security research and should not trigger cybersecurity safeguards.

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 2026-07-08T03:26:05.590Z.
