T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The RTF document 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 upon opening the document. This activation likely triggers the execution of a malicious payload, consistent with a spearphishing attachment. No scripts were extracted, but the OLE object's behavior points towards exploitation for client execution.
Heuristics 3
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF 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_OBJUPDATERTF 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_OBJDATARTF contains 2 \objdata section(s) — embedded OLE objects
