MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The document contains heuristics indicating it attempts to load a remote template and an external object from a URL. This suggests the document is designed to download and execute a second-stage payload. The presence of a remote image beacon also points to tracking or command and control communication.

Heuristics 5

  • MSHTML-style external object relationship critical CVE related OFFICE_MSHTML_EXTERNAL_OBJECT
    External relationship to http://canarytokens.com/images/sq0ggof80xaiwvc6kd28np42s/index.html — exploitable MSHTML/CAB/MHTML/HTA-style Office attack surface
  • External relationship high OOXML_EXTERNAL_REL
    External target in word/_rels/footer2.xml.rels: http://canarytokens.com/images/sq0ggof80xaiwvc6kd28np42s/index.html
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://cdn.discordapp.com/attachments/873792563868479538/890241120251019264/Template1L) — 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.
  • Remote image (web beacon / tracking pixel) medium OOXML_IMAGE_BEACON
    Document references an external image URL — loads automatically on open, revealing IP address and timestamp to the server (used for phishing tracking and NTLM hash theft on corporate networks)
  • 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.
