MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a malicious OOXML document that uses external relationships and hyperlinks to point to a remote template. This suggests an attempt to trick the user into downloading a malicious template, likely for further exploitation. The presence of external hyperlinks and remote template injection indicates a phishing or social engineering attempt.

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 (3) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 3 external hyperlinks — clickable URLs are stored as external relationships. First target: http://ww3.fca.gov/readingrm/handbook/FCA Regulation/614.4240.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.
