MITRE ATT&CK
T1203 Exploitation for Client Execution
The RTF file contains embedded OLE object data and specifically triggers heuristics related to the Equation Editor vulnerability (CVE-2017-11882). This vulnerability allows for arbitrary code execution when the embedded object is activated. The ClamAV detection further confirms the presence of this exploit. No document body or script content was available for further analysis.
Heuristics 5
-
Equation Editor CLSID critical CVE likely 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.
-
