T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects that are automatically linked and updated, indicating an attempt to execute embedded content. The heuristic firings strongly suggest the use of OLE object manipulation to achieve code execution. While no specific script was extracted, the OLE object data itself is likely malicious, potentially leading to a secondary payload download or execution. The confidence is high due to the multiple high-severity RTF heuristics firing.
Heuristics 4
-
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.
-
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 2 \objdata section(s) — embedded OLE objects
