T1204.002 Malicious File
T1059.001 PowerShell
The RTF document contains OLE object data and uses \objupdate to force OLE activation, indicating a likely exploit. The Ole10Native stream further suggests embedded malicious content. While no specific payload or URL was extracted, the heuristics strongly point to a malicious RTF file designed to exploit OLE vulnerabilities for code execution, commonly used for downloading further stages.
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 2 \objdata section(s) — embedded OLE objects
