MITRE ATT&CK
T1204 Malicious Link T1059 Command and Scripting Interpreter

The sample exhibits high-severity heuristics for remote template injection and external relationship, both pointing to the URL http://ir.cx/XeHTq. This indicates the document is designed to fetch and likely execute content from this external source, a common technique for malware delivery. No document body text or scripts were extracted, but the heuristics strongly suggest a malicious intent to download a secondary payload.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://ir.cx/XeHTq) — 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://ir.cx/XeHTq
  • 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.
