When the user clicks on the link that accompanies the message, he or she is redirected to a page that asks for personal data, such as full name, email and phone, and is induced to grant permission to receive future notifications, which may present new scams. The disseminated text also asks the victim to share the message with five WhatsApp contacts. Finally, the affected person is directed to pages with fraudulent advertisements.
According to dfndr lab director Emilio Simoni, scams that take advantage of real government programs are common, and do many casualties.

It is also important to be wary of very advantageous or under-priced promises common to scams.
