The RTF document contains OLE objects with embedded data, and a \objupdate directive forces OLE activation. This indicates an attempt to exploit OLE vulnerabilities to execute embedded code. The high entropy of the Ole10Native stream suggests it may contain a packed or encrypted payload. Without further analysis of the OLE object's content, the exact nature of the payload remains unclear, but the exploit pattern is consistent with malicious code execution.
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
