MITRE ATT&CK
T1204.002 Malicious File

The file exhibits remote template injection and external relationship heuristics, both pointing to the URL https://42url.com/hB5zzdli. ClamAV identifies the file as Doc.Downloader.Redline-9972754-0, suggesting it functions as a downloader. The primary attack pattern involves luring the user to access the external resource which likely leads to a second-stage payload download.

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://42url.com/hB5zzdli) — 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://42url.com/hB5zzdli
  • 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.
