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

The file exhibits characteristics of a malicious OOXML document, specifically by referencing a remote template. This suggests an attempt to load external content, likely for malicious purposes such as downloading a secondary payload or executing arbitrary code. The presence of external hyperlinks and relationships further supports this, indicating the document is designed to interact with external resources.

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 (2) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 2 external hyperlinks — clickable URLs are stored as external relationships. First target: file:///M:/Federal Register Documents/2019-02650.pdf
  • 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.
