MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a DOCX document that uses remote template injection and external relationships to load a malicious template from 'http://ms-work.com-info.store/dms/0203.dotm'. The document body contains what appears to be financial transaction details, likely a lure to encourage the user to open or interact with the malicious content. No scripts were extracted, but the heuristics strongly indicate a malicious template download.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://ms-work.com-info.store/dms/0203.dotm) — 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://ms-work.com-info.store/dms/0203.dotm
  • 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://ms-work.com-info.store/dms/0203.dotm
