T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF document contains embedded OLE objects with `\objupdate` directives, indicating an attempt to exploit OLE activation for code execution. The high entropy of the decoded OLE object suggests it contains executable content, likely a secondary payload. The `RTF_OLE10NATIVE_STREAM` heuristic further confirms the presence of a potentially malicious OLE object.
Heuristics 4
-
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
-
