MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The critical ClamAV detection for 'Doc.Tool.Phishery-6331699-0' strongly suggests this document is part of the Phishery toolkit, which is used for phishing attacks. The heuristics for remote template injection and external relationships, pointing to 'https://transfer.sh', indicate the document is designed to load external content, likely a malicious payload. The minimal document body text does not provide further context, but the combination of the detection and heuristics points to a phishing lure designed to execute a secondary stage.

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://transfer.sh) — 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://transfer.sh
  • 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.
