    Document references a remote template URL (http://usa-national.info/USA/precision.dot) — 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 target in word/_rels/settings.xml.rels: http://usa-national.info/USA/precision.dot
  • External hyperlinks (65) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 65 external hyperlinks — clickable URLs are stored as external relationships. First target: file:///E:\20210727_Weekly_Epi_Update_50.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.
