The RTF file contains OLE object data and triggers an OLE activation heuristic, indicating it's designed to exploit OLE vulnerabilities. The presence of ".objdata" and ".objupdate" sections strongly suggests an embedded OLE object is being used to deliver a payload. No readable document body or scripts were extracted, making it difficult to determine the exact user-facing lure or the specific payload, but the mechanism points to code execution.
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 1 \objdata section(s) — embedded OLE objects
