MTN assured the public that the confidentiality, integrity, and availability of its systems remain central to its operations.

The company noted that it is working closely with leading cybersecurity experts and has devoted significant resources to contain and manage the incident.

Customers have been advised to remain vigilant by updating mobile and banking applications, using strong passwords, enabling multifactor authentication, and avoiding the disclosure of sensitive information such as passwords, PINs, and OTPs through phone calls, text messages, or emails.
