T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains OLE object data and uses \objupdate to force OLE activation, indicating an attempt to exploit a vulnerability. The presence of the Ole10Native stream further supports this, suggesting the embedded OLE object is malicious and likely designed to execute code. This points towards a malicious attachment used for initial compromise, potentially to download 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
