[Bug][aup] Authorized malware analysis skill for anti-reversing technique study blocked mid-session

Type: AUP / Usage-Policy block (false positive) · Work domain (heuristic): malware-forensics

Why this is a false positive

This automated cyber-safeguard fired on an authorized, in-scope malware-forensics workflow: the request involved invoking a clearly-gated anti-reversing/analysis skill that requires confirmed written authorization before use, applied to defensive reverse-engineering of a sample. The block keys on dual-use technique keywords ("bypass," "anti-reversing," "analysis") without weighing the explicit authorization gate or the legitimate forensic context, so it misclassifies routine defensive analysis as offensive abuse. The result is a hard refusal on standard, permitted security research, with no way to supply the authorization context that would resolve the false positive inline.

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 2026-05-27T03:03:57.692Z.
