MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a malicious OOXML document that uses remote template injection and external relationships to load content from the URL https://hyp.ae/qmP8n. This technique is commonly used to download and execute secondary payloads, as indicated by the ClamAV detection of 'Doc.Downloader.Redline'. The document body is minimal and does not provide further 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://hyp.ae/qmP8n) — 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://hyp.ae/qmP8n
  • 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.
