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.

Structural branches: 2 STICH kept: 1secondary ignored: 1

bin 1

Decorative / non-determinant leaves (styles, themes, media, fonts, icons, plain text…) are summarized here instead of producing STICH Paths.

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