Le e-mail apparentemente inviate da uffici federali o imprese conosciute come Swisscom, ma che in realtà sono copie più o meno ben realizzate, sono in aumento. La segnalazione è del MELANI, il servizio della Confederazione per l'analisi e la sicurezza dell'informazione, che mette in guardia: aprire l'allegato porta all'installazione sul computer di programmi malevoli, sia che si disponga di un sistema operativo Windows che di un Mac.
Ci sono il caso del presunto rimborso d'imposte a condizione di riempire un formulario o la promessa di inesistenti prestazioni, si afferma nell'avvertimento. I messaggi fraudolenti in circolazione nel mondo sono centinaia di migliaia.
L'obiettivo dei truffatori è quello di destabilizzare le vittime, inducendole a cliccare sul documento. La raccomandazione può essere solo una: prudenza. Bisogna riflettere bene prima di agire e in caso di dubbio contattare il presunto mittente.
