MITRE ATT&CK
T1204.002 Malicious File

The file is identified as malicious by ClamAV and exhibits characteristics of remote template injection and external relationship usage. The presence of these heuristics suggests the document is designed to pull content from an external source, likely to download and execute a secondary payload. The URL associated with these heuristics, while marked as benign, is still considered a potential indicator of compromise in this context.

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://is.gd/DjSoAL) — 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://is.gd/DjSoAL
  • 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.
