T1566.001 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious File
The RTF file contains OLE object data and an \objupdate command, indicating an attempt to exploit OLE activation. The heuristic firings strongly suggest that this mechanism is used to embed and execute an external artifact, likely a secondary payload. The truncated document body prevents a more specific determination of the lure, but the technical indicators point to a malicious OLE object execution.
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
-
