T1203 Exploitation for Client Execution
T1059.001 PowerShell
The sample is an RTF document containing embedded OLE objects, specifically triggering heuristics for Equation Editor exploitation and OLE object activation. This indicates a likely attempt to exploit a known vulnerability in the Equation Editor component to achieve code execution. The embedded OLE object data suggests the potential for a secondary stage, such as downloading and executing a payload, although no specific URLs or scripts were extracted to confirm this.
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.
-
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
-
\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
