These attacks are made when a WhatsApp user changes their phone, he/she will have to verify that the new device is linked to his/her mobile number. This is done through WhatsApp verification code. The hacker knows the user’s mobile number and this whole series of attacks begins with the victim shares his WhatsApp verification code, he allows the hacker to gain access to his account.
Once the victim’s account is hacked, the cyber criminal gets access to all his contacts as well as groups. A chain reaction begins after this.
Such cases of crime have been reported in other states as well where criminals have extorted money by hacking WhatsApp.
Cyber investigators and experts advise people not to share their WhatsApp verification code with anyone. If you share the verification code, then immediately re-verify your WhatsApp account. Further, users are also advised to activate ‘two-step verification’ for enhancing the security of their WhatsApp accounts and do not open links sent by unknown people.
