MITRE ATT&CK
T1204.002 Malicious File: User Execution

The file is identified as malicious by ClamAV and exhibits critical heuristic firings for remote template injection and external relationships. These indicate the document is designed to fetch and execute content from a remote source, specifically the URL https://filingrimm.com/ecm/ibm/3149569888/converter.dot, which is likely a secondary payload or exploit. The document body content is truncated and does not provide further context on the lure.

Heuristics 4

  • ClamAV: Doc.Downloader.Office3steps12210-9915225-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Office3steps12210-9915225-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://filingrimm.com/ecm/ibm/3149569888/converter.dot) — 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://filingrimm.com/ecm/ibm/3149569888/converter.dot
  • 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.
