MITRE ATT&CK

T1559.001 Component Object Model T1204.002 Malicious File

The RTF file contains OLE object data with an \objupdate directive, indicating an attempt to activate embedded objects. This is a known technique for exploiting vulnerabilities in OLE object handling to achieve code execution. The presence of decoded OLE object data further supports this attack vector. No specific family could be identified.

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
