The file is an RTF document containing OLE object data, as indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this embedded object is designed to be activated, likely leading to the execution of malicious code. The presence of objdata suggests a downloader or exploit delivery mechanism. Without further script analysis or document body content, the exact payload and delivery method remain unclear, leading to a moderate confidence score.

Heuristics 2
