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

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to exploit OLE object activation. This suggests the file is designed to deliver a payload via a vulnerability, likely through a spearphishing attachment. No document body text or scripts were available for further analysis, limiting the ability to determine the specific payload or family.

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
