The RTF file contains multiple high-severity heuristic firings related to OLE object data, automatic linking, and updates, indicating the exploitation of OLE vulnerabilities. The presence of `RTF_OLE10NATIVE_STREAM` suggests an embedded OLE object that is likely designed to execute code or download a secondary payload. The document body is heavily obfuscated and does not provide clear textual lures. Therefore, the primary attack vector appears to be the exploitation of OLE object vulnerabilities within the RTF structure.
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
