SIM swapping, or SIM card fraud

During a SIM swap or SIM card exchange, an ill-intentioned person could recover the SMS code sent by the Delubac bank to validate your banking transactions without you knowing.

How do hackers do it? Having previously collected certain personal information about you, such as your first name, last name and address, they will pretend to be you when contacting your telecom operator and tell them that your SIM card has been stolen or lost.

They can then receive single-use codes and steal your identity.

To combat this, if you observe an unusual prolonged loss of network:

• Contact your telecom operator immediately;
  
• Immediately change your online access password;
  
• Contact your manager immediately
