The RTF document contains embedded OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated automatically, which is a common technique for exploiting vulnerabilities in applications that process OLE objects, such as Microsoft Office. The embedded object data itself is the primary indicator of compromise.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE
