MITRE ATT&CK
T1204.002 Malicious File: User Execution

The file exhibits critical heuristics for remote template injection and external relationships, indicating it is designed to fetch content from a remote source. The ClamAV detection as 'Doc.Downloader.Redline-9972754-0' strongly suggests its purpose is to download and execute a secondary payload. The embedded URL, despite its unusual format, is the primary indicator of this malicious activity.

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://OOOW3OOOOOOO233OOOOOO23OO33B2OB32O32O32B3O23BO33O3S0DFSDF0X000F0SD0000WLLL21LLLLL222LLLLL3333LELLL@267199949/e2....................do) — 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://OOOW3OOOOOOO233OOOOOO23OO33B2OB32O32O32B3O23BO33O3S0DFSDF0X000F0SD0000WLLL21LLLLL222LLLLL3333LELLL@267199949/e2..
  • 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.
