MITRE ATT&CK
T1204.002 Malicious File

The sample exhibits critical heuristic firings for remote template injection and external relationships, both pointing to a suspicious URL. This indicates the document is designed to fetch and likely execute a secondary payload from the identified remote resource. The ClamAV detection as 'Doc.Downloader.Redline-9972754-0' further supports its role as a downloader.

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 (http://users@3236162770/...-.------------------------.-.-.-.--.-.-----------------______---.-/.......98.doc) — 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 high OOXML_EXTERNAL_REL
    External target in word/_rels/webSettings.xml.rels: http://users@3236162770/...-.------------------------.-.-.-.--.-.-----------------______---.-/.......98.doc
  • 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.
