    ClamAV detected this file as malware: Doc.Downloader.Redline-9972754-0

    Document references a remote template URL (https://rb.gy/zcva7e) — 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/webSettings.xml.rels: https://rb.gy/zcva7e
  • 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.
