A message recently shared on social media suggested that we should not check our mobile money account balance right after receiving a scam call. And that’s a rule everyone should follow, according to mobile operators.
They explained that the scammer triggers a cash withdrawal operation remotely with your number and then calls you pretending he has mistakenly made a deposit in your account, asking you to send him back the money. Right after that call, our first reaction is to check our balance, entering our PIN code and thus approving the scammer’s operation, without even knowing it.
“This is the mistake you should not make.. Indeed, the hacker has already triggered a withdrawal process on your phone before calling you. When you try to check your account balance, you will come across the withdrawal confirmation message that he has already initiated. Of course, you won't pay any attention and you'll enter your Pin code. As soon as you do, you give him access to your money,” a source at MTN Cameroon explained.
To avoid this, it is recommended to wait at least 15 minutes before checking your account, because “that's the time it takes for the withdrawal message to expire.” You should always check the message for which you are about to enter your secret code or you can just type in a wrong code, which will cancel the operation initiated by the hacker. It is also recommended to ask the person calling you to call the customer service and explain his request.
