The RTF document contains multiple high-severity heuristics indicating the exploitation of OLE object activation. Specifically, RTF_OBJDATA, RTF_OBJAUTLINK, and RTF_OBJUPDATE suggest that embedded OLE objects are being automatically activated. The presence of RTF_OLE10NATIVE_STREAM further confirms that a native OLE object is embedded, which is likely the mechanism for delivering a malicious payload. The document body is heavily obfuscated and does not provide clear textual clues, but the heuristics strongly point to an attack pattern involving the execution of embedded content.
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
