MITRE ATT&CK
T1203 Exploitation for Client Execution
The RTF document contains an embedded OLE object with OLE10Native stream data, which is a common technique for delivering exploits. The ".bin" file extracted from the OLE object is highly suspicious and likely contains shellcode or a secondary payload. The presence of OLE object data and the forced activation via \objupdate strongly suggest an attempt to execute code upon opening the document.
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 1 \objdata section(s) — embedded OLE objects
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
