MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file was detected as malicious by ClamAV with the signature 'Doc.Tool.Phishery-6331699-0', indicating it is likely a Phishery-based attack. Heuristics indicate the use of remote template injection and external relationships, pointing to the URL 'https://secure.site.local/docs' as the source for loading external content. This suggests the document is designed to trick the user into loading a remote template, which in turn likely downloads and executes a secondary payload.

Heuristics 4

  • ClamAV: Doc.Tool.Phishery-6331699-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Tool.Phishery-6331699-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://secure.site.local/docs) — 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/settings.xml.rels: https://secure.site.local/docs
  • 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.
