MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV and exhibits characteristics of a downloader. It attempts to inject a remote template from the URL 'https://silindigam.top/ecm/ibm/3755614780/converter.dot', indicating it's designed to fetch and execute a secondary payload. This behavior aligns with spearphishing attachments used to deliver malware.

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://silindigam.top/ecm/ibm/3755614780/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://silindigam.top/ecm/ibm/3755614780/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.
