This puts billions of WhatsApp users at risk since a hacker could remotely deactivate your account and restrict you from activating it again. This security flaw can reportedly be exploited even if you are using two-factor authentication (2FA) for your WhatsApp account.

According to security researchers  Luis Márquez Carpintero and Ernesto Canales Pereña, the flaw exists due to two fundamental weaknesses. The first weakness allows the hacker to gain access to your phone number. This will not give the hacker access to your WhatsApp account, since they won’t have the 6 digit code you will get on your phone.

However, multiple failed attempts with the wrong code would block code entries for the hacker on his WhatsApp app. The attacker will then be able to contact WhatsApp support to deactivate your phone number from the app. They will only need a new email address and a simple email saying that the phone has been lost or stolen.

In response, the hacker will get an email from WhatsApp for confirmation to which they can quickly respond. This will deactivate your account even if you have 2FA enabled.
