T1204.002 Malicious File
The RTF document contains embedded OLE objects that are triggered for activation via \objupdate. This indicates an attempt to exploit OLE object handling to execute arbitrary code. The specific nature of the embedded object is not fully discernible from the provided heuristics, but the presence of \objdata and \objupdate strongly suggests a malicious intent to leverage OLE for code execution, likely as a downloader or initial execution vector.
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
