MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV and exhibits heuristics for remote template injection and external relationships. These indicators point to an attempt to load content from the URL http://188.34.187.110/g0xqtv.dotm, which is likely a malicious template designed to execute further stages of an attack. The primary attack pattern observed is the use of a malicious document to lure the user into downloading and executing a payload.

Heuristics 4

  • ClamAV: Doc.Downloader.e341431ebcbc3c3a-9980308-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.e341431ebcbc3c3a-9980308-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://188.34.187.110/g0xqtv.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: http://188.34.187.110/g0xqtv.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.
