MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to force OLE activation. This is a common technique for executing embedded malicious code. While the specific payload is not directly visible, the presence of these indicators strongly suggests an exploit for client execution, likely as part of a spearphishing attachment.

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 2 \objdata section(s) — embedded OLE objects
