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

The RTF document contains OLE object data and is configured to automatically update and activate these objects upon opening. This suggests a malicious intent to execute embedded code, likely for payload delivery. While no specific script was extracted, the heuristics strongly indicate an exploit targeting OLE object activation. The confidence is moderate due to the lack of directly executable script content.

Heuristics 3

  • Automatically linked OLE object high RTF_OBJAUTLINK
    RTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
  • \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
