The file is an RTF document containing OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this OLE object is designed to be activated automatically, likely exploiting a vulnerability to execute code. The presence of OLE object data strongly suggests an attempt to deliver a malicious payload via a document. No specific family could be identified, and the document body was unreadable.

Heuristics 2
