MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious File

The RTF document contains OLE object data and an \objupdate directive, indicating it's designed to activate embedded objects. This is a common technique for delivering malicious payloads. While no specific script or URL was directly extracted, the presence of these RTF-specific heuristics strongly suggests an attempt to execute embedded code or trigger a download. The confidence is moderate due to the lack of explicit payload delivery details.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE
    RTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
