Financial fraud rarely happens without warning. In most cases, criminals spend days or even weeks quietly observing a target before making their move. They test small transactions, gather information, and patiently wait for the right moment. Learning to recognize the early warning signs can be the difference between catching a threat early and waking up to an empty account.
Fraudsters are patient. They watch, they test, and they wait. Your job is to notice before they strike.
Sign One: Small Unexplained Transactions
One of the first things fraudsters do after gaining partial access to your account is test it with tiny transactions, sometimes as small as ten or twenty naira or a few cents. These micro-transactions confirm the account is active and the details are valid. Most people ignore small charges thinking it is a bank fee or a forgotten subscription.
Check every single transaction on your statement, no matter how small - Question any charge you do not immediately recognize - Call your bank if you see a transaction from a merchant you have never used
Sign Two: Unexpected Password Reset Emails
If you start receiving password reset emails for your bank, email, or financial accounts that you did not request, someone is attempting to gain access. This is an active attack in progress, not a random glitch.
Change your email password immediately - Enable two-factor authentication on your email account - Alert your bank that unauthorized access may be attempted
Sign Three: Your Phone Suddenly Loses Network
A sudden, unexplained loss of mobile network while your phone is fully charged and in a normal location can be a sign of SIM swapping. This is a technique where a criminal convinces your mobile network to transfer your phone number to a SIM card they control, giving them access to all your SMS verification codes.
Contact your mobile network immediately if this happens - Ask your network provider to add a SIM swap lock to your account - Switch to an authenticator app instead of SMS for two-factor verification
Sign Four: You Stop Receiving Bank Alerts
If your transaction alerts suddenly stop arriving but your account is still active, your contact details may have been changed by someone with unauthorized access. Banks send alerts to the registered email and phone number — if those details have been quietly changed, you will stop receiving notifications.
Sign Five: Calls From Your Bank You Did Not Initiate
Receiving an unexpected call from someone claiming to be your bank is a major red flag. Real banks rarely call customers out of nowhere asking for personal verification details.
Conclusion
Your account is worth protecting before a crisis, not after one. Set up alerts, monitor your statements weekly, and treat every unexplained event as a potential warning signal. Fraudsters count on your inattention. Your attention is your greatest defense.
