The RTF document contains OLE object data and an instruction to enable editing, which are common tactics for delivering malicious payloads. The heuristic 'SE_ENABLE_LURE' specifically indicates that the document attempts to trick the user into enabling macros or content. This suggests the file is designed to exploit user interaction to execute further malicious actions.

Heuristics 3

  • Macro/content-enable lure medium SE_ENABLE_LURE
