The sample is an RTF document containing embedded OLE objects, with heuristics indicating that \objupdate forces OLE activation. This suggests the document is designed to exploit OLE vulnerabilities or features to execute embedded code. The presence of an embedded OLE object, decoded from objdata, strongly implies an attempt to deliver a secondary payload or exploit. Without further script analysis or network indicators, the exact family and final payload remain undetermined.
Heuristics 3
-
\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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
