MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The RTF file contains embedded OLE objects, indicated by the RTF_OBJDATA and RTF_OLE10NATIVE_STREAM heuristics. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated automatically, which is a common technique for executing embedded exploits or scripts. While no specific script content was extracted, the presence of OLE objects strongly implies an attempt to exploit vulnerabilities or deliver a secondary payload, aligning with spearphishing attachment tactics.

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
