How to read this, and where it stops

SPECIMEN reports indicators, never a verdict, because every sign it can see appears in honest software too. High entropy means packing, not guilt; injection APIs are in security tools as well as implants. Use it to decide what deserves an analyst's time. Its blind spot is packing: a compressed or encrypted sample hides its real code and strings until it unpacks in memory, which static reading cannot reach - SPECIMEN will say it is packed, and a sandbox is the next step. VOUCH checks whether a signature is genuine and who it names.
