T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains an embedded OLE object that leverages the Equation Editor, indicated by the RTF_EQUATION_EDITOR heuristic. The RTF_OBJAUTLINK and RTF_OBJUPDATE heuristics suggest that this object is designed to be activated automatically upon opening, likely exploiting a known vulnerability such as CVE-2017-11882. The document body, though partially encoded, contains text related to marketing and strategy, suggesting a lure to trick the user into enabling content and triggering the exploit.
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.
-
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 1 \objdata section(s) — embedded OLE objects
