The OOXML file contains heuristics indicating remote template injection and external relationship exploitation, both pointing to the URL http://chilp.it/e4aa8de. This suggests the document is designed to download and execute a secondary payload from this external source, likely leading to further malicious activity.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://chilp.it/e4aa8de) — a common remote-template-injection vector used by Hancitor, Emotet and many phishing campaigns. Word can fetch and apply the remote template; macros in that template may execute depending on Office policy and trust state.
  • External relationship medium OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: http://chilp.it/e4aa8de
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
