Zenith Bank has confirmed a cyber attack on its database that resulted in unauthorized access to some customer information.
In an official email sent to customers on Tuesday, August 4, 2026, the financial institution disclosed that hackers compromised contact details. However, the bank maintains that core banking functions and funds remain safe.
Key Facts of the Security Incident
• Exposed Data: The accessed information includes customer email addresses and phone numbers.
• Core Systems Intact: Zenith Bank assured the public that no sensitive financial data, passwords, or PINs were compromised.
• Operational Status: All digital channels, mobile apps, and banking services remain fully secure and functional.
• Context: The lender stated that the breach is part of a broader global cyberattack targeting organizations across multiple sectors.
Independent Ransomware / Threat Actor Claims
While Zenith Bank officially reports the breach as “limited”, cybersecurity monitoring platforms noted that a threat group known as Exfilsquad claimed responsibility for a massive breach on Zenith Bank.
The group alleged online that they exfiltrated up to 874 GB of records containing deeper personal and financial data. These expansive claims remain unverified by regulatory authorities or official banking statements.
Crucial Steps to Protect Your Account
Because phone numbers and emails were leaked, fraudsters are highly likely to launch targeted phishing campaigns.
Customers are thus encouraged to:
*Ignore unsolicited calls: Do not trust anyone calling to “verify” or “rectify” an issue with your Zenith Bank account.
* Keep credentials private: Never share your OTP, Password, ATM PIN, or Hardware Token codes with anyone. Zenith Bank staff will never ask for them.
* Check links closely: Avoid clicking on web links sent via SMS or email claiming your account is blocked or restricted.
* Use official channels: If you experience an issue, communicate only through verified handles like the official Zenith Bank Customer Support Page or authorized phone lines.
