MITRE ATT&CK
T1204.002 Malicious File

The document exhibits characteristics of a malicious OOXML file, specifically triggering heuristics for remote template injection and external relationships. These indicators suggest an attempt to load external content, likely to exploit a vulnerability or download a secondary payload. The presence of embedded EMF files further supports the possibility of malicious content. The primary IOC is the URL associated with the remote template injection heuristic.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://jamp.to/5TVQZm) — 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: https://jamp.to/5TVQZm
  • 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.
    URL http://schemas.openxmlformats.org/markup-compatibility/2006
