T1059.001 PowerShell
T1204.002 Malicious File
The RTF document contains OLE object data, which is a common technique for embedding malicious content. The heuristics indicate that the OLE object is likely activated via \objupdate, suggesting an attempt to execute embedded code or trigger a download. Without further script analysis or network indicators, the exact payload and delivery mechanism remain unclear, leading to an 'unknown family' classification.
Heuristics 4
-
\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
-
