T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains embedded OLE objects, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be automatically activated upon opening the document. This mechanism is commonly used to drop and execute a secondary payload, hence the high confidence in an initial payload delivery attack pattern. No specific family could be identified.
Heuristics 3
-
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 1 \objdata section(s) — embedded OLE objects
