MITRE ATT&CK
T1204 Malicious File T1059 Command and Scripting Interpreter

The file exhibits characteristics of a downloader, specifically using remote template injection via the URL http://1806435511/..----------..----------------.---------.--------/443.dothtml. This technique is often used to fetch and execute a secondary payload. ClamAV detection as Doc.Downloader.Redline-9972754-0 further supports this assessment.

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://1806435511/..----------..----------------.---------.--------/443.dothtml) — 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/webSettings.xml.rels: http://1806435511/..----------..----------------.---------.--------/443.dothtml
  • 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.
