\nPer un attacco \u00e8 possibile legare una macro a un gestore di eventi, attivato ad esempio al passaggio del cursore del mouse su una determinata area o con l'attivazione del focus di input nel documento (evento onFocus). Di conseguenza, aprendo un documento preparato dall'attaccante \u00e8 possibile eseguire in modo invisibile codice Python, senza che l'utente se ne accorga. Ad esempio, nell'esempio dimostrativo dell'exploit, all'apertura del documento si avvia senza avviso la calcolatrice di sistema.
