The RTF document contains OLE object data and an \objupdate directive, indicating it's designed to activate embedded objects. The document body presents a lure about financial audits, instructing the user to 'Enable editing' and implicitly macros, a common technique for malware droppers. No scripts were extracted, and no specific IOCs were identified beyond the file itself.
