[Bug][cyber] Safety block on AES/RC4 key analysis for unpacking a protected Android DEX binary (req_011CcWUjkz41RRupNdBuycUZ)

Triage: kind cyber · domain general · 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

The blocked conversation involved static analysis of a compiled binary — specifically locating encryption key candidates in a shared library's data section and attempting to decrypt a protected payload — which is standard mobile security research and reverse-engineering methodology. No exploit development, network attack tooling, or harmful capability was being produced; the work was purely analytical (read-only inspection of an existing artifact). The block appears to have triggered on surface-level cybersecurity vocabulary (key extraction, AES/RC4, DEX unpacking) without accounting for the defensive/research context in which those techniques were being applied.

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 2026-06-28T22:53:03.194Z.
