MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains multiple indicators of malicious OLE object embedding, specifically targeting the Equation Editor component. The presence of \objupdate and SE_ENABLE_LURE heuristics suggests the document is designed to trick the user into activating the embedded object, which likely exploits a known vulnerability to execute a payload. No scripts were extracted, and the document body content appears to be legitimate marketing material, indicating the lure is external to the visible text.
Heuristics 5
-
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
-
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
