T1059.001 PowerShell
The RTF document contains multiple high-severity heuristic firings indicating the exploitation of OLE object vulnerabilities, specifically RTF_OBJAUTLINK and RTF_OBJUPDATE, which force OLE activation. The presence of RTF_OLE10NATIVE_STREAM further suggests embedded malicious content within the OLE object. While no specific script was extracted, the combination of these heuristics strongly implies an attack pattern designed to automatically execute embedded code, likely for downloading and running a secondary payload.
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
