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

The OOXML document contains a remote template injection and an external relationship pointing to the URL https://go.ox4.in/9i5i7. This indicates the document is designed to fetch and execute content from an external source, likely a malicious payload. The heuristics suggest a macro-based delivery mechanism, common for initial access.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://go.ox4.in/9i5i7) — 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: https://go.ox4.in/9i5i7
  • 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.
