MITRE ATT&CK

T1559.001 Component Object Model T1204.002 Malicious File

The RTF document contains OLE object data and uses \objupdate to force OLE activation, indicating an attempt to exploit a vulnerability. The presence of the Ole10Native stream further supports this. While no specific exploit or payload is directly visible, the structure strongly suggests an exploit delivery mechanism.

Heuristics 3

Ole10Native stream in RTF OLE object high CVE related RTF_OLE10NATIVE_STREAM

RTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
\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
