MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The document exhibits characteristics of a malicious macro-enabled file, specifically using a remote template injection and an external relationship to a OneDrive URL, which is a common delivery vector. The 'SE_ENABLE_LURE' heuristic indicates that the document itself instructs the user to enable macros or editing, a typical tactic to bypass security measures. This suggests the document's primary purpose is to trick the user into enabling malicious content, likely to download and execute a second-stage payload from the provided OneDrive URL.

Heuristics 5

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://onedrive.live.com/download?cid=4C1669F22428D4FE&resid=4C1669F22428D4FE!129&authkey=AL_9Z3sgNwjdZmU&em=2) — 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://onedrive.live.com/download?cid=4C1669F22428D4FE&resid=4C1669F22428D4FE!129&authkey=AL_9Z3sgNwjdZmU&em=2
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • External hyperlinks (40) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 40 external hyperlinks — clickable URLs are stored as external relationships. First target: http://www.newadvent.org/cathen/15364a.htm
  • 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.
