MITRE ATT&CK
T1566.001 Spearphishing Attachment

The OOXML document contains heuristics indicating remote template injection and external relationships pointing to a suspicious URL. This suggests the document is designed to lure the user into downloading and executing a malicious payload from the specified external resource. No scripts were extracted, but the presence of the external URL is a strong indicator of malicious intent.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://45.121.146.88/Apricot/Main.jpg) — 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: http://45.121.146.88/Apricot/Main.jpg
  • 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.
