WhatsApp users warned over 'nasty' scam that gives hackers full access to your account

A stern warning has been issued regarding a 'nasty' WhatsApp scam that can end with hackers gaining complete control over users' accounts.

This warning was given by consumer champions at Which?, who warned: "This nasty scam continues to circulate and could result in scammers taking over your account". The scam is initiated when you receive a legitimate text message from WhatsApp containing a verification code.

This possibly means fraudsters may have used your number on WhatsApp in an attempt to gain access to your account which triggers the code text. Following this message, a contact from your WhatsApp list messages you through the app, often with a concocted story to persuade you to hand over the verification code - they could even claim to have mistakenly inputted your number.

This fraudulent act tricks many into sharing the verification code as the request appears to be from a known contact, thus granting the con artists access to the compromised accounts, reports Wales Online.

According to Which?, following hacking the account, scammers identify the victim's frequently contacted numbers from their message history and solicit them for money or sensitive details. They might also uncover personal information about you and your associates from your chatlogs.

This information could be used to access other important accounts, target you with more scams, or even blackmail you. Scammers are likely to carry out the same trick with verification codes with the new set of contacts they've unlocked, gaining access to more and more accounts.

Which? advice on how to keep your WhatsApp account safe.

• Don’t share your login details or verification code with anybody. Not even your closest family or trusted friends.

• Set up two-step verification to secure your account.

• Report spam messages or block the sender within WhatsApp. Press and hold on the message bubble, select ‘Report’ and then follow the instructions.

• Be wary of WhatsApp messages requesting money, even if they come from your contacts. If you’re not sure, give the friend a quick call to check.

If you think you may have given sensitive details to fraudsters, let your bank know immediately. WhatsApp users who have lost access to their accounts can contact support@whatsapp.com.

If you have been a victim of fraud or cyber crime, report it to Action Fraud online or by calling 0300 123 2040.
