MITRE ATT&CK
T1204.002 Malicious File

The file is identified as malicious by ClamAV and exhibits characteristics of remote template injection and external relationships, pointing to a downloader. The embedded URL 'https://transfer.sh/get/KgHDsr/s3g53o.dotm' is highly suspicious and likely serves as the source for a secondary payload. The document body itself does not contain exploitable content, but the heuristics strongly indicate a malicious intent to fetch and execute external code.

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 (https://transfer.sh/get/KgHDsr/s3g53o.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://transfer.sh/get/KgHDsr/s3g53o.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.
