The file is an RTF document that exploits the Equation Editor vulnerability. It contains a lure to enable editing, which is a common technique for macro-based malware droppers. The presence of OLE object data and the ".objupdate" directive strongly suggest that the document is designed to trigger an embedded exploit, likely leading to the download and execution of a second-stage payload.
Heuristics 4
-
Split hex Equation Editor ProgID + OLE object critical RTF_EQUATION_EDITORRTF embeds the Equation.3 ProgID as hex bytes near OLE object activation and splits the byte stream with whitespace or an ignorable RTF group. This is an Equation Editor OLE activation surface commonly used by CVE-2017-11882 / CVE-2018-0802 exploit documents.
-
\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
-
Macro/content-enable lure medium SE_ENABLE_LUREDocument instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
