T1204.002 Malicious File
T1059.001 PowerShell
The RTF document contains OLE object data that is automatically linked and updated, indicating an attempt to execute embedded content. The high entropy of the extracted artifact suggests it is likely a payload. Without further script analysis or network indicators, the specific family and ultimate goal remain unclear, but the technique points towards a malicious OLE object execution.
Heuristics 4
-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\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
