CIBN partial database leak claimed on DarkForums

Overview

A DarkForums thread from 1 July 2025 claims that a partial database of the Chartered Institute of Bankers of Nigeria (CIBN), the professional body for bankers in Nigeria, has been compromised and made available for download. The leak is said to include sensitive information of some banking professionals.

What was published

The poster describes the dataset as a partial database covering banking professionals in Nigeria. CIBN, incorporated in 1976 and chartered in 1990, regulates the banking profession and maintains records of its members. The captured page includes an image, and a download is offered in the thread.

Risks for affected individuals

Professional records of bankers can include names, contact details, qualifications, and membership identifiers. Exposure could enable phishing targeting financial sector professionals, who are high-value targets for fraudsters.

What remains unknown

The size of the partial database and the fields it contains are not disclosed. Whether financial or account information is included is unclear, and CIBN has not publicly responded.

What affected people should do

Banking professionals in Nigeria should be alert to phishing messages referencing CIBN or their professional credentials. Monitoring for identity misuse and using strong, unique passwords for professional accounts is advised.
