MITRE ATT&CK
T1204 Malicious File T1059 Command and Scripting Interpreter

The file exhibits characteristics of a malicious OOXML document, specifically triggering heuristics for remote template injection and external relationships pointing to 'https://s.id/1JPZH'. This suggests the document is designed to fetch and execute content from this external URL, likely a secondary payload. The presence of embedded OLE objects further supports a malicious intent.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://s.id/1JPZH) — 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://s.id/1JPZH
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • 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.
