MITRE ATT&CK
T1204.002 Malicious File

The OOXML document contains heuristics indicating remote template injection and external relationship manipulation. These point to an attempt to download and execute a secondary payload from the URL http://104.168.32.38/doc_office/60.doc. The document body itself does not contain user-facing text, but the heuristics strongly suggest a malicious download and execution chain.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://104.168.32.38/doc_office/60.doc?&men=frightened&kleenex=hot&disease=statuesque&washbasin=confused&elephant=upbeat&scooter=miscreant&t) — 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://104.168.32.38/doc_office/60.doc?&men=frightened&kleenex=hot&disease=statuesque&washbasin=confused&elephant=upbeat
  • 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.
    URL http://104.168.32.38/doc_office/60.doc?&men=frightened&kleenex=hot&disease=statuesque&washbasin=confused&elephant=upbeat&scooter=miscreant&t
