The RTF document contains embedded OLE object data that is automatically updated and activated. This indicates an attempt to exploit vulnerabilities within the RTF parsing or OLE object handling to execute arbitrary code. The heuristic firings strongly suggest the presence of an embedded OLE object designed for automatic execution, likely serving as a dropper for further malicious activity.
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
