Heuristics 5

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://logp.fmv.se/tjansterprodukter/mpub/Documents/Forms/Document/Processdokument.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: https://logp.fmv.se/tjansterprodukter/mpub/Documents/Forms/Document/Processdokument.dotx
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • External hyperlinks (15) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 15 external hyperlinks — clickable URLs are stored as external relationships. First target: http://logistikportalen.fmv.se/tjansterprodukter/mpub/SitePages/ProcessB.aspx?processId=B1 Teknisk order
  • 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.
