T1203 Exploitation for Client Execution
T1027 Obfuscated Files or Information
The file is an RTF document containing embedded OLE objects, specifically triggering heuristics related to Equation Editor and OLE object activation. ClamAV explicitly identifies this as Rtf.Exploit.CVE_2017_11882-6584355-1, indicating exploitation of the CVE-2017-11882 vulnerability. This vulnerability allows for arbitrary code execution when the embedded object is activated.
Heuristics 6
-
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
-
ClamAV: Rtf.Exploit.CVE_2017_11882-6584355-1 critical CLAMAV_DETECTIONClamAV detected this file as malware: Rtf.Exploit.CVE_2017_11882-6584355-1
-
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
