In many cases, all they need is your phone number, your BVN, a leaked password, a fake WhatsApp message, or a successful trick to convince you to reveal sensitive information.

Common Banking Fraud Threats in Nigeria
1. Phishing Attacks
Phishing is a cyberattack where criminals impersonate a trusted organization such as a bank to trick victims into revealing confidential information. Example, you receive an SMS claiming:
"Your account has been suspended. Click here immediately to reactivate." The link takes you to a fake banking website that looks identical to your bank's website. Once you enter: "Username" "Password" "ATM card details" "OTP code," the fraudster gains access to your account and carryout whatever they want to do.
How to Stay Safe

- Verify messages directly with your bank.
- Type your bank's website manually.
- Ignore urgent messages demanding immediate action.
2. SIM Swap Fraud
SIM swap fraud remains one of the most dangerous banking threats in Nigeria.
How It Works
Fraudsters gather personal information about a victim and convince a telecom provider to transfer the victim's phone number to a new SIM card. Once successful: Your phone loses network service. Fraudsters receive your OTPs. They reset banking passwords. They authorize transactions, warning signs, sudden loss of network signal, inability to receive calls or SMS, and mobile banking login issues.
Protection Tips

Example: A scammer pretending to be a bank representative asks you to "verify" your account by providing your account number, BVN, ATM card details, or OTP code. No legitimate bank employee should request these details.
Protection Tips

- Never share OTPs.
- Enable WhatsApp Two-Step Verification.
