T1204.002 Malicious File
T1566.001 Spearphishing Attachment
The RTF document contains embedded OLE objects, indicated by RTF_OBJDATA and RTF_OLE10NATIVE_STREAM heuristics. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated automatically upon opening the document. This mechanism is commonly used to execute embedded code, often to download and run further malicious stages. The specific nature of the embedded content could not be fully determined due to truncation, but the heuristics strongly indicate a malicious intent.
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
