T1566.001 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious File
The RTF file contains OLE object data and an \objupdate directive, indicating it's designed to activate embedded objects. This strongly suggests a malicious intent to exploit OLE vulnerabilities or deliver a payload. While no specific family is identifiable, the technique points towards a downloader or exploit delivery mechanism. The extracted objdata artifact is flagged as suspicious and is the primary IOC.
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
-
