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

The RTF file contains embedded OLE object data and triggers an \objupdate event, indicating an attempt to exploit a vulnerability for code execution. The heuristics suggest a classic RTF object embedding exploit. Without further script or URL evidence, the specific payload and delivery mechanism remain unclear, but the intent is to leverage the OLE object for malicious execution.

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
