The RTF document contains OLE object data and an instruction to update the OLE object, indicating an attempt to execute embedded content. The document body provides a lure related to financial audits, instructing the user to 'click Enable editing', which is a common tactic to bypass security measures and execute malicious macros or scripts. No scripts were extracted, but the heuristics strongly suggest the document is designed to trick the user into enabling content execution.

Heuristics 3

  • \objupdate forces OLE activation high RTF_OBJUPDATE

  • Macro/content-enable lure medium SE_ENABLE_LURE
