Malware Insights

The file uses remote template injection and external relationships to load content from a suspicious URL. The ClamAV detection indicates this is a downloader, likely attempting to retrieve and execute a second-stage payload from the identified URL. The document body content is minimal and does not provide further context.

Heuristics 4

  • ClamAV: Doc.Downloader.Redline-9972754-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Redline-9972754-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://kungeducationalinvestment8tusdyagender.duckdns.org/office/invoice_11155.doc) — 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 high OOXML_EXTERNAL_REL
    External target in word/_rels/webSettings.xml.rels: http://kungeducationalinvestment8tusdyagender.duckdns.org/office/invoice_11155.doc
  • 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.
