MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file exhibits critical heuristic firings for remote template injection and external relationships, indicating an attempt to load external content. The ClamAV detection as 'Doc.Downloader.Redline-9972754-0' strongly suggests a downloader functionality. The embedded URLs point to a suspicious IP address, likely serving as the source for a second-stage payload. No scripts were extracted, but the heuristics and detection name imply a downloader role.

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://198.12.91.160/--...........................................------..................--------/...........................-.............) — 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://198.12.91.160/--...........................................------..................--------/.....................
  • 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.
