MITRE ATT&CK
T1204.002 Malicious File

The file exhibits characteristics of a downloader, specifically triggering heuristics for remote template injection and external relationships pointing to the URL https://myown.bio/ioh. ClamAV detection as 'Doc.Downloader.Redline-9972754-0' strongly suggests the Redline family. The primary attack vector appears to be leveraging external resources to fetch and execute further malicious content.

Heuristics 4

  • ClamAV: Doc.Downloader.Redline-9972754-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Redline-9972754-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://myown.bio/ioh) — 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/webSettings.xml.rels: https://myown.bio/ioh
  • 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.
