The RTF document contains multiple high-severity heuristics indicating the presence of OLE object data that is automatically linked and updated, suggesting an attempt to exploit vulnerabilities. The embedded OLE object data, decoded as objdata_00_off00000fa1.bin, is a strong indicator of malicious intent. While no specific script was extracted, the RTF object manipulation points towards a delivery mechanism for further malicious payloads.
Heuristics 4
-
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
-
