MITRE ATT&CK
T1204.002 Malicious File T1059.001 PowerShell

The file exhibits critical heuristic firings for ClamAV detection as 'Doc.Downloader.Redline-9972754-0', indicating it's a downloader. High-severity heuristics for OOXML remote template injection and external relationship point to the URL http://domainsecuritycheckingforcloudfilesharei.duckdns.org/wd/document_b_1200.doc as the source of the malicious payload. The document body contains minimal content, suggesting the primary malicious functionality relies on the external resource.

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://domainsecuritycheckingforcloudfilesharei.duckdns.org/wd/document_b_1200.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://domainsecuritycheckingforcloudfilesharei.duckdns.org/wd/document_b_1200.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.
