T1559.001 Component Object Model Hijacking
T1204.002 Malicious File
The RTF document contains OLE object data that is automatically linked and updated, indicating an attempt to exploit vulnerabilities associated with OLE object activation. The presence of `RTF_OBJDATA`, `RTF_OBJAUTLINK`, `RTF_OBJUPDATE`, and `RTF_OLE10NATIVE_STREAM` heuristics strongly suggests that the embedded OLE object is designed to execute malicious code upon opening the document. No scripts were extracted, and the document body content is heavily obfuscated and truncated, preventing a more specific analysis of the payload's intent.
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 1 \objdata section(s) — embedded OLE objects
