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

The RTF document contains OLE object data and uses automatic linking and update mechanisms, indicating an attempt to exploit vulnerabilities or activate embedded objects. While no specific payload or script was directly extracted, these heuristics strongly suggest a malicious intent to execute code upon opening. The lack of readable document body text or scripts limits further analysis of the exact delivery mechanism or payload.

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
