MITRE ATT&CK
T1204.002 Malicious File: User Execution

The sample exhibits OOXML remote template injection and external relationship heuristics, indicating it attempts to load content from a remote URL. The embedded URL `http://192.3.110.133/office_doc/115.doc?&hamaki=level&infusion=gaudy&uzbekistan=yummy&sack=known&ironclad=icky&plywood=creepy&funny` is likely used to download and execute a secondary malicious payload. The document body itself does not contain exploitable content, but the heuristics strongly suggest a malicious intent.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://192.3.110.133/office_doc/115.doc?&hamaki=level&infusion=gaudy&uzbekistan=yummy&sack=known&ironclad=icky&plywood=creepy&funny) — 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://192.3.110.133/office_doc/115.doc?&hamaki=level&infusion=gaudy&uzbekistan=yummy&sack=known&ironclad=icky&plywood=c
  • 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.
