MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample is an OOXML document that uses remote template injection and external relationships to reference a malicious DOCX file. This indicates an attempt to trick the user into downloading a secondary malicious payload. The specific content of the document body was truncated, preventing a more detailed analysis of the lure.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://netmediaresources.com/IsisAttackinNewYork.docx) — 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/webSettings.xml.rels: http://netmediaresources.com/IsisAttackinNewYork.docx
  • 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.
