MITRE ATT&CK
T1059.001 PowerShell

The file is identified as malicious due to the presence of a remote template injection heuristic, indicating an attempt to download a malicious template from an external URL. The embedded URL points to 'http://kasim.freedynamicdns.org/root/backups/IVCbXw.dot', which is likely the malicious payload. The document body contains text that appears to be official correspondence, potentially to add legitimacy to the lure.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://kasim.freedynamicdns.org/root/backups/IVCbXw.dot) — 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/settings.xml.rels: http://kasim.freedynamicdns.org/root/backups/IVCbXw.dot
  • 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.
