T1059.001 PowerShell
The RTF document contains OLE object data and is configured to automatically update and activate these objects, indicating an attempt to exploit embedded vulnerabilities. The presence of `RTF_OBJDATA`, `RTF_OBJAUTLINK`, and `RTF_OBJUPDATE` heuristics strongly suggests a malicious RTF exploit. The extracted artifact `objdata_00_off0000122b.bin` is likely the payload or exploit code. Without further analysis of the embedded object, the exact family remains unknown, but the attack pattern points towards a classic RTF exploit delivery mechanism.
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
-
