Zenith Bank has confirmed that it experienced a cybersecurity breach that resulted in unauthorised access to limited customer information, including email addresses and phone numbers.

The bank disclosed the incident in a notification sent to customers on Tuesday, explaining that the attack formed part of a wider global cyber campaign targeting organisations across various sectors.

According to the bank, the compromised data was limited to basic customer contact information and did not include sensitive banking credentials or financial records.

Zenith Bank assured customers that its banking services and digital platforms remain secure and fully operational despite the incident.

The financial institution said it immediately activated its cybersecurity response procedures upon detecting the breach and has launched a full investigation to determine the circumstances surrounding the attack.

As investigations continue, the bank urged customers to remain vigilant against phishing attempts, warning them not to disclose passwords, Personal Identification Numbers (PINs), One-Time Passwords (OTPs) or any other security credentials through emails, phone calls or text messages.

Zenith Bank reaffirmed its commitment to protecting customer information and expressed appreciation for the continued trust and support of its customers while efforts to investigate the incident continue.

The breach follows growing concerns over cyber threats targeting financial institutions. In 2024, Guaranty Trust Bank (GTBank) also reported an attempted cyberattack on its website domain, although it maintained that customer data was not compromised.

The development also comes after the Central Bank of Nigeria warned members of the public about the rise in cyber fraud schemes involving fake emails and messages designed to steal personal and financial information by impersonating the apex bank.
