T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF document contains OLE object data and uses \objupdate to force OLE activation, indicating an attempt to exploit a vulnerability for client execution. The presence of the Ole10Native stream further supports this. The specific exploit mechanism is not detailed, but the overall pattern suggests a malicious attachment designed to compromise the user's system.
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 1 \objdata section(s) — embedded OLE objects
