MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file exhibits characteristics of a malicious document downloader, specifically triggering heuristics for remote template injection and external relationships pointing to the URL https://itsssl.com/VLafV. ClamAV also identified it as Doc.Downloader.Redline-9972754-0. The presence of these indicators suggests the document is designed to fetch and execute a second-stage payload from the identified URL, likely as part of a spearphishing campaign.

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://itsssl.com/VLafV) — 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://itsssl.com/VLafV
  • 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.
