MITRE ATT&CK
T1204.002 Malicious File: User Execution T1559.001 Component Object Model Hijacking

The RTF file contains an embedded OLE object with an \objupdate directive, which is a known technique for triggering embedded exploits. This suggests the file is designed to execute arbitrary code when opened, likely leading to a second-stage payload. The specific exploit targeted is not immediately clear from the heuristics alone.

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
