MITRE ATT&CK
T1566.001 Spearphishing Attachment

The OOXML document contains external hyperlinks and a remote template reference, indicating an attempt to load external resources. The heuristic 'OOXML_REMOTE_TEMPLATE' strongly suggests that the document is configured to load content from 'http://fcahome/readingrm/handbook/FCA Regulation/Forms/template.dotx', which is a common technique for delivering malicious payloads or redirecting users. The presence of an external hyperlink to 'http://ww3.fca.gov/readingrm/fedreg/Federal Register Documents/71 FR 44410.docx' further supports the malicious intent.

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 (1) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 1 external hyperlink — clickable URLs are stored as external relationships. First target: http://ww3.fca.gov/readingrm/fedreg/Federal Register Documents/71 FR 44410.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.
