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 related to financial auditing, instructing the user to 'Enable editing', a common tactic to bypass macro security. This suggests the document is a dropper intended to execute a malicious payload via the embedded OLE object.

    RTF contains 1 \objdata section(s) — embedded OLE objects
  • Macro/content-enable lure medium SE_ENABLE_LURE
