MITRE ATT&CK
T1559.002 Component Object Model and Distributed Component Object Model
The RTF document contains OLE objects that are automatically linked and updated, indicating an attempt to exploit vulnerabilities associated with OLE activation. The presence of multiple \objdata sections and an Ole10Native stream further supports this. No scripts were extracted, and the document body was not available, limiting further analysis of the specific payload.
Heuristics 5
-
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
-
