T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains OLE object data that is forced to activate via \objupdate, indicating an attempt to exploit OLE object handling. The presence of the Ole10Native stream further supports this. While no specific script was extracted, the heuristics strongly suggest the embedded OLE object is malicious and likely attempts to download and execute a secondary payload.
Heuristics 3
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
-
\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
