Nigerian police have warned citizens against using free and public Wi-Fi networks for sensitive online activities, particularly banking transactions, over concerns about cybersecurity and the possible theft of personal information.
The warning urged Nigerians to exercise caution when connecting their mobile phones and other devices to public internet networks, especially those provided in public places where users may not know who operates or controls the connection.
According to the warning, people who use free Wi-Fi for banking transactions could expose themselves to cybercriminals who may exploit insecure networks to steal sensitive information, compromise accounts or gain unauthorised access to their financial details.
“Avoid using free and public Wi-Fi. If you want to use free Wi-Fi, make sure you are using a VPN to protect yourself,” the warning stated.
It further cautioned that using public Wi-Fi for banking activities could put users at risk of having their accounts compromised.
Cybersecurity experts have repeatedly advised internet users to avoid accessing sensitive financial services through unsecured public networks. Depending on the network’s security and the methods used by attackers, information such as login credentials and other personal details may be exposed.
Nigerians have therefore been advised to use trusted mobile data connections or secure private networks when carrying out financial transactions online.
Where public Wi-Fi is unavoidable, users should consider using a reputable virtual private network (VPN), ensure that websites and applications use encrypted connections, and avoid clicking suspicious links or downloading unfamiliar applications.
However, a VPN does not provide complete protection against every cyber threat, making it important for users to adopt additional security measures.
Bank customers are also encouraged to activate transaction notifications, use strong and unique passwords, enable multi-factor authentication where available, and never disclose their banking PINs, passwords or one-time passwords (OTPs) to anyone.
The warning comes amid growing concerns about online fraud and the need for Nigerians to strengthen their digital security habits as internet-based banking and financial transactions continue to expand.
