T1204.002 Malicious File
The RTF file contains embedded OLE objects that are forced to activate via \objupdate. This indicates a technique to execute embedded code or launch an embedded file. The presence of \objdata and \OLE10NATIVE_STREAM further supports the malicious nature of the embedded object. While no specific script was extracted, the heuristics strongly suggest the OLE object is designed to execute a secondary payload, likely leading to further system compromise.
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.
-
\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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
