MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The RTF document contains embedded OLE objects, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated automatically or upon user interaction, which is a common technique for delivering malicious payloads. The document body is heavily obfuscated and does not provide clear textual clues about its intent. Without further script analysis or network indicators, the exact payload and delivery mechanism remain unclear, but the OLE object activation is the primary attack vector.
