MITRE ATT&CK
T1204.002 Malicious File

The file exhibits high-severity heuristics for remote template injection and external relationships, both pointing to the URL http://198.23.207.54/shp/doc_200.doc. ClamAV detection further confirms its malicious nature as a downloader. The embedded OLE object suggests a complex payload delivery mechanism.

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://198.23.207.54/shp/doc_200.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://198.23.207.54/shp/doc_200.doc
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • 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.
