LAGOS AUGUST 5TH (NEWSRANGERS)-Zenith Bank Plc is investigating an incident involving unauthorised access to customers’ data, noting that the breach does not involve financial information and has not compromised its banking services or digital channels.
In an email sent to customers on Wednesday, the bank stated that the incident was part of a broader global cyberattack affecting multiple international organisations across various sectors.
The lender stated that it immediately activated its incident response protocols and intensified its cybersecurity and remediation efforts upon discovering the incident.
“This incident is part of a broader, global cyber-attack targeting multiple international organisations across various sectors. Upon discovery, we promptly activated our incident response protocols, cybersecurity actions and remediation efforts,” the bank said.
The bank reassured customers that its banking services and digital channels remain secure and fully operational.
As a precautionary measure, Zenith Bank advised customers to remain alert to potential phishing attempts and other forms of social engineering.
“As a precaution, we encourage our customers to remain vigilant against phishing emails, text messages, or phone calls, and never to disclose their password, PIN, One-Time Password (OTP), or other security credentials to anyone,” the bank said.
The incident is the latest in a series of cybersecurity challenges facing Nigerian financial institutions, with banks in recent months suspending their social media operations over impersonation and other fraudulent activities.
Earlier in April, the Nigeria Data Protection Commission (NDPC) said it was investigating alleged data breaches involving Sterling Bank, Remita and the Corporate Affairs Commission (CAC).
Nigerian banks have long been prime targets for cybercriminals because of the vast amounts of customer data and financial transactions they handle every day.
While many attacks have traditionally sought to steal funds, cybercriminals are increasingly targeting personal information, which can be used for identity theft, phishing schemes, account takeovers and other forms of financial fraud.
Cybersecurity threats have increasingly targeted Nigerian banks in recent years. In 2025, Union Bank of Nigeria warned customers about fraudulent websites and phishing campaigns designed to steal login credentials and personal information by impersonating the bank.
In August 2024, Guaranty Trust Bank experienced a domain-related security incident that temporarily disrupted access to its official website, although the lender assured customers that their deposits and banking services remained secure while it resolved the issue.
