MITRE ATT&CK
T1203 Exploitation for Client Execution
T1059.001 PowerShell
The RTF file contains an embedded OLE object, specifically triggering critical heuristics for Equation Editor CLSID and objupdate, indicating exploitation of CVE-2017-11882. This vulnerability allows for arbitrary code execution. The presence of an extracted OLE object suggests it's used to deliver a secondary payload, likely for further system compromise.
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
-
\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
-
