The file is an RTF document containing OLE object data and specifically targets the Equation Editor vulnerability. The presence of the SE_ENABLE_LURE heuristic indicates a user-enablement lure, suggesting the document's primary purpose is to trick the user into activating malicious content. No scripts were extracted, and the document body was heavily obfuscated, making further analysis of the payload difficult.
Heuristics 5
-
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
-
