The RTF document contains embedded OLE objects that are triggered for activation via \objupdate. This indicates an attempt to exploit OLE object vulnerabilities to execute arbitrary code. The specific nature of the payload is not clear from the static analysis, but the technique strongly suggests a malicious intent, likely to download and execute a secondary payload or establish a foothold on the system. Confidence is moderate due to the lack of script content for definitive payload analysis.
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.
-
\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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
