How to protect yourself from online banking fraud in Nigeria
Meanwhile, TheRadar earlier compiled a detailed practical guide on how to protect yourself from online banking fraud in Nigeria.
With the growth of digital banking, scammers are using phishing messages, fake apps and social engineering to steal money and sensitive information from unsuspecting users.
Never share PINs, OTPs or passwords, and avoid clicking on suspicious links, as fraudsters often impersonate banks to trick users into revealing confidential information.
Use strong passwords, enable two-factor authentication, avoid public Wi-Fi for banking, and regularly check your account for unusual transactions to detect fraud early.
