MITRE ATT&CK
T1204.002 Malicious File

The file exhibits characteristics of a downloader, specifically flagged by ClamAV as 'Doc.Downloader.Redline-9972754-0'. The presence of 'OOXML_REMOTE_TEMPLATE' and 'OOXML_EXTERNAL_REL' heuristics, along with the embedded URL 'https://ggle.io/4FaS', strongly suggests that this document is designed to fetch and execute a secondary payload. The primary attack pattern involves luring the user into opening the document, which then initiates the download process.

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://ggle.io/4FaS) — 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://ggle.io/4FaS
  • 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.
