The new scam in Whatsapp follows a very simple modus operandi. The only thing the user suddenly receives is a sms similar to the one sent by the application when it activates the account in a new device. Most likely the user will receive this message without having previously requested it and this can only mean two things, that someone is trying to impersonate our account or that the virus has reached our phone.
The most important thing is not to click on the link that includes this sms because, if we do, the person who sent the sms can enter our Whatsapp account and access all our conversations. If this happens, every time we try to enter the application from our phone we will receive a message that will tell us that the phone is no longer registered.
