MITRE ATT&CK
T1204.002 Malicious File

The critical ClamAV heuristic indicates detection as 'Doc.Downloader.Redline-9972754-0', suggesting a downloader. The 'OOXML_REMOTE_TEMPLATE' and 'OOXML_EXTERNAL_REL' heuristics firing on the URL 'https://cutt.ly/AbgTkBa' strongly suggest the document is configured to fetch and execute content from this external source. This pattern is consistent with a malicious document designed to download and run a secondary stage 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 (https://cutt.ly/AbgTkBa) — 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://cutt.ly/AbgTkBa
  • 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.
