MITRE ATT&CK
T1203 Exploitation for Client Execution

The RTF document contains OLE object data and a \objupdate directive, which are commonly used to trigger the execution of embedded exploits. This suggests the file is designed to exploit vulnerabilities in OLE object handling to achieve code execution. No specific family could be identified, and no further IOCs were extracted.

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
