MITRE ATT&CK
T1204.002 Malicious File

The file is a malicious OOXML document that leverages remote template injection and external relationships to fetch content from an external URL. The heuristics indicate a high likelihood of remote template injection, suggesting the document is designed to download and execute a secondary payload from the specified URL. The embedded EMF files are likely part of the exploit chain.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://url.terryspace.io/suBWx7) — 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://url.terryspace.io/suBWx7
  • 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.
