The sample uses a remote template injection and external relationship heuristic, indicating it attempts to pull content from an external URL. The document body presents a list of parts, likely as a lure to encourage macro enablement. ClamAV detected this as a downloader, and the embedded URL is suspicious, suggesting it downloads and executes a second-stage payload.

Heuristics 5

  • ClamAV: Doc.Downloader.Loda-7570590-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Loda-7570590-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://87.121.221.212/secdukaszx.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/settings.xml.rels: http://87.121.221.212/secdukaszx.doc
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • 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.
