MITRE ATT&CK
T1204 Malicious File T1059 Command and Scripting Interpreter

The sample exhibits high-severity heuristics for remote template injection and external relationship, indicating an attempt to load external content. ClamAV detection as 'Doc.Downloader.Redline-9972754-0' strongly suggests the Redline family and a downloader functionality. The embedded URL is likely used to fetch and execute a malicious payload.

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://00o0o0o0sdf000000ooOOOO0000000ooooooooOOOOOsdoo000oo@647601465/13.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://00o0o0o0sdf000000ooOOOO0000000ooooooooOOOOOsdoo000oo@647601465/13.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.
