T1059.001 PowerShell
The RTF document contains multiple indicators of malicious OLE object embedding, specifically RTF_OBJDATA, RTF_OBJAUTLINK, and RTF_OBJUPDATE. These heuristics suggest that the document is designed to automatically activate and update an embedded OLE object when opened. This mechanism is commonly used to download and execute a second-stage payload. No specific family could be identified, and no URLs or scripts were extracted to further detail the payload or its delivery mechanism.
Heuristics 3
-
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 2 \objdata section(s) — embedded OLE objects
