MITRE ATT&CK
T1204.002 Malicious File

The sample exhibits characteristics of a malicious OOXML document, specifically triggering heuristics for remote template injection and external relationships. The presence of the URL 'https://kutt.chatforma.com/e1Hw5I' strongly suggests an attempt to load external content, which is a common technique for downloading and executing further malicious stages. No document body text or scripts were extracted, limiting the ability to determine the exact nature of the payload.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://kutt.chatforma.com/e1Hw5I) — 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://kutt.chatforma.com/e1Hw5I
  • 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.
