MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment

The OOXML document was flagged for remote template injection and external relationship, both pointing to the URL http://31.220.4.124/payload-final.docx. This indicates the document is designed to download and execute a secondary payload from this location. The presence of embedded URLs further supports this delivery mechanism. No scripts were extracted, but the heuristics strongly suggest a malicious download attempt.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://31.220.4.124/payload-final.docx) — 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/webSettings.xml.rels: http://31.220.4.124/payload-final.docx
  • 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.
