MITRE ATT&CK
T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF document contains OLE object data and triggers an \objupdate event, indicating an attempt to exploit a vulnerability related to OLE object activation for code execution. The presence of an embedded OLE object, objdata_00_off00000d33.bin, further supports this. The document's content is heavily obfuscated and appears to be a lure, likely delivered via spearphishing.
Heuristics 3
-
\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
-
