MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a malicious OOXML document that leverages external relationships and remote templates to potentially load malicious content. The presence of external hyperlinks suggests an attempt to redirect the user or download additional payloads. The document's structure and heuristics indicate a likely spearphishing attachment used to deliver further malicious content.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://fcahome/readingrm/handbook/FCA Regulation/Forms/template.dotx) — 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://fcahome/readingrm/handbook/FCA Regulation/Forms/template.dotx
  • External hyperlinks (4) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 4 external hyperlinks — clickable URLs are stored as external relationships. First target: http://ww3.fca.gov/readingrm/handbook/FCA Regulation/611.330.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.
    URL http://ww3.fca.gov/readingrm/handbook/FCA Document hyperlink
