Majority of users who have voicemail activated, have their passwords set either 0000 or 1234. Using this flaw, hackers can easily hijack your WhatsApp account by adding your number to a new WhatsApp account using a different smartphone. But how exactly does this work? The cyber security authority has offered some clarity around it.

Bar-Zik, an Israeli web developer said that WhatsApp has a security protocol where it will send an SMS code to the given handset number for authentication purposes. However, this layer can be skipped when the user is not around the smartphone.

After several failed attempts to get the SMS code, WhatsApp will verify the account using voice verification. At this point, a call will be made to the user s number, and one-time code will be spoken out loud. If the user does not answer the call, it will go to voicemail. To get this code, the hacker can simply enter the code and get going. This will allow hackers to use your WhatsApp account and number without any permissions. The hacker can then enable two-step verification (in case you don t already have it enabled), and lock out the original user from accessing the account.

So, what s the solution? To being with, security experts recommend using a complex password for your voicemail account. Secondly, you should also enable two-step verification for your WhatsApp account to make it extra secure, and add a layer of protection.
