MITRE ATT&CK
T1203 Exploitation for Client Execution
The RTF file contains embedded OLE objects, specifically triggering critical heuristics related to Equation Editor exploitation. This indicates the file is designed to leverage a known vulnerability in the Equation Editor component to achieve arbitrary code execution upon opening. No document body or scripts were extracted, limiting further analysis of the payload.
Heuristics 5
-
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.
-
Equation Editor CLSID critical RTF_EQUATION_EDITOREquation Editor OLE CLSID found inside an OLE object — exploited by CVE-2017-11882 / CVE-2018-0802 / CVE-2018-0798
-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\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
