T1203 Exploitation for Client Execution
The RTF document contains embedded OLE objects, specifically triggering critical heuristics related to Equation Editor and automatic OLE activation. This strongly indicates the use of a known vulnerability within the Equation Editor component to achieve arbitrary code execution upon opening the document. No specific family could be identified, and no further IOCs were extracted.
Heuristics 4
-
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 2 \objdata section(s) — embedded OLE objects
