MITRE ATT&CK
T1204.002 Malicious File

The OOXML_REMOTE_TEMPLATE and OOXML_EXTERNAL_REL heuristics indicate that the document is configured to fetch content from an external URL. This URL, http://87.120.84.39/txt/casseyofficefile.dot, is highly suspicious and likely serves as a lure for a secondary payload or exploit. The document body contains garbled text, suggesting it's not intended for direct user interaction but rather to facilitate the remote template injection.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://87.120.84.39/txt/casseyofficefile.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://87.120.84.39/txt/casseyofficefile.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.
