MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The file is an RTF document containing embedded OLE objects, specifically triggering critical heuristics related to Equation Editor exploitation. The presence of \objdata and \objupdate commands indicates an attempt to force OLE object activation, likely leading to the execution of a malicious payload via a known Equation Editor vulnerability. No document body text or scripts were extracted, but the heuristics strongly suggest a classic exploit document.
Heuristics 3
-
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 2 \objdata section(s) — embedded OLE objects
