MITRE ATT&CK
T1204.002 Malicious File

The file is identified as malicious due to the high-severity heuristic firing for OOXML_REMOTE_TEMPLATE, indicating an attempt to inject a remote template from 'http://mishel.freedynamicdns.org/boot/mail/yopWWb.dot'. This suggests the document is designed to lure the user into downloading and executing a malicious template, likely leading to further compromise. The OOXML_EXTERNAL_REL heuristic further supports this by indicating an external relationship that could be leveraged for malicious purposes.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://mishel.freedynamicdns.org/boot/mail/yopWWb.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://mishel.freedynamicdns.org/boot/mail/yopWWb.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.
