MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample exhibits characteristics of a malicious OOXML document, specifically remote template injection and external relationship firings pointing to 'https://outlook.officebetas.com/isis.png'. This suggests the document is designed to lure the user into downloading and executing a secondary payload from the specified URL, likely as part of a spearphishing campaign.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://outlook.officebetas.com/isis.png) — 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://outlook.officebetas.com/isis.png
  • 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.
