T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF document contains OLE object data and triggers an automatic update, indicating it's designed to exploit OLE object activation for code execution. The presence of `RTF_OBJAUTLINK` and `RTF_OBJUPDATE` heuristics strongly suggests this mechanism. The embedded OLE object, `objdata_00_off00000e21.bin`, is the primary artifact facilitating this exploit, likely serving as a dropper for further malicious activity.
Heuristics 3
-
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
