MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The file is identified as malicious by ClamAV and exhibits characteristics of remote template injection and external relationship usage, pointing to the download of a malicious template. The presence of a remote template URL strongly suggests an attempt to lure the user into downloading and executing a secondary payload, consistent with spearphishing attachment tactics.

Heuristics 4

  • ClamAV: Win.Malware.Agent-8015286-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Malware.Agent-8015286-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://od.lk/d/MzBfMjA1Njc0ODdf/pubmaterial.dotm) — 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://od.lk/d/MzBfMjA1Njc0ODdf/pubmaterial.dotm
  • 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.
