Free public Wi-Fi is becoming an integral part of everyday digital life across Nigeria, connecting millions of people in cafés, restaurants, airports, shopping centres, universities and other public spaces. 

But as internet access becomes more accessible, cybersecurity experts are warning that the convenience comes with significant privacy and security risks that many users neither recognise nor understand.

Nigeria’s telecoms market has continued its growth trajectory, providing the digital connectivity that underpins the widespread use of public Wi-Fi services across the country. According to the latest industry statistics released by the Nigerian Communications Commission (NCC), active telephone subscriptions rose to 188.01 million in April 2026, while active internet subscriptions climbed to 154.35 million, reflecting sustained demand for mobile voice and data services.

The Nigerian telecoms regulator also reports that broadband penetration reached 55.67%, highlighting the growing reliance of the population on digital connectivity for banking, e-commerce, remote work, education and social networking.

The rapid expansion of internet access has also increased demand for free public Wi-Fi hotspots in cafés, restaurants, airports, hotels, university campuses and shopping centres, where users often seek to reduce mobile data costs or access faster connections. 

While these networks support Nigeria’s digital inclusion goals by extending internet access beyond mobile broadband, cybersecurity experts warn that their growing popularity has also widened the attack surface for cybercriminals. 

As more Nigerians conduct financial transactions and access sensitive online services over public networks, industry analysts say stronger cybersecurity awareness is becoming just as important as expanding digital connectivity in safeguarding the country’s digital economy.

But for millions of Nigerians seeking to reduce mobile data costs, connecting to a free wireless network has become almost instinctive. Yet experts say the same networks that offer convenient internet access can also provide cybercriminals with opportunities to intercept personal information, steal credentials and compromise sensitive online accounts.

The growing concern reflects a broader challenge facing Nigeria’s digital transformation agenda: while internet access continues to expand, public awareness of basic cybersecurity practices has not kept pace.

Why public Wi-Fi poses a cybersecurity risk

Unlike mobile broadband connections, which are individually secured between a subscriber and a telecoms provider, public Wi-Fi networks are typically shared by dozens, or even hundreds, of users at the same time.

This shared environment, technology security analysts say, makes it easier for attackers connected to the same network to observe or manipulate internet traffic, particularly where the network lacks strong security controls or users access websites and applications without adequate encryption.

For Hazadat Barakat Oyindamola, a cybersecurity analyst at Utica, internet users have little practical way of verifying whether a public Wi-Fi hotspot is genuine or has been created by cybercriminals to lure unsuspecting victims. “There’s absolutely no way you can identify whether a public Wi-Fi network is legitimate or potentially malicious,” she says, explaining that once a network is publicly accessible, virtually anyone can connect.

According to cybersecurity experts, one of the biggest challenges for ordinary users is that malicious wireless networks are often virtually indistinguishable from legitimate ones.

“There’s absolutely no way you can identify whether a public Wi-Fi network is legitimate or potentially malicious,” she says, explaining that once a network is publicly accessible, virtually anyone can connect.

That openness creates opportunities for attackers to quietly position themselves alongside legitimate users, monitoring internet activity or attempting to intercept sensitive information without attracting attention, she cautions.

Financial and personal accounts most at risk

Cybersecurity specialists say not every online activity presents the same level of exposure. However, certain accounts represent particularly attractive targets because of the financial or personal information they contain.

Online banking platforms rank among the highest-risk services. “The most vulnerable,” Oyindamola says, “is your bank account because that’s where your money is.” 

Email accounts are another major concern because they often serve as the gateway to numerous other online services. Once attackers gain access to an email account, they may be able to reset passwords, impersonate victims, distribute phishing emails or launch additional attacks against friends, colleagues or family members.

Social media accounts can also be exploited to spread fraudulent investment schemes, impersonation scams and other forms of cyber-enabled fraud.

Global cybersecurity firms warn of evolving attacks

The risks highlighted by Nigerian cybersecurity experts mirror warnings issued by global cybersecurity companies, including Kaspersky, which has repeatedly cautioned users about the dangers associated with unsecured public wireless networks.

Cybercriminals, Kaspersky warns, commonly exploit public Wi-Fi through techniques such as man-in-the-middle attacks, rogue or fake hotspots and data interception.

In these attacks, criminals may capture unencrypted internet traffic, steal usernames and passwords or redirect victims to fraudulent websites designed to harvest banking credentials and other sensitive information.

The tech security company also notes that cybercriminals frequently exploit the trust users place in familiar public locations, including cafés, airports, hotels and shopping centres, where free internet access is routinely offered. One particularly deceptive tactic involves creating fake wireless networks with names that closely resemble legitimate ones, making it extremely difficult for users to distinguish between genuine and malicious connections.

As Oyindamola notes, “As long as it is public, there is going to be an open gap to exploit it.”

How Nigerians can use public Wi-Fi more safely

Despite the risks, cybersecurity professionals emphasise that public Wi-Fi is not inherently unsafe if users adopt appropriate security practices.

One of the most effective protective measures is using a reputable Virtual Private Network (VPN), which encrypts internet traffic between a user’s device and the internet, making intercepted data significantly more difficult for attackers to read.

However, experts caution that not all VPN services provide the same level of protection. Some free VPN applications have themselves been linked to questionable data collection practices and malicious software, making reputable paid services the safer choice where privacy is a priority.

“Always use VPN… although there’s no 100% safe VPN, at least you are safer to some extent,” Oyindamola advises.

Cybersecurity experts also recommend that users:

• Avoid accessing banking platforms or other financial services while connected to public Wi-Fi.

• Refrain from logging into email accounts or other sensitive online services on unsecured networks.

• Disable automatic connections to open Wi-Fi hotspots.

• Avoid entering passwords, payment details or other confidential information unless using a trusted, encrypted connection.

• Restrict public Wi-Fi use to low-risk activities such as reading news or browsing publicly available content.

Balancing digital inclusion with cyber resilience

Nigeria’s expanding availability of public Wi-Fi supports broader national objectives around digital inclusion, internet accessibility and economic participation. Free wireless connectivity enables students, entrepreneurs, remote workers and consumers to access online services while reducing data costs.

However, experts argue that expanding digital access must be accompanied by stronger public awareness of cybersecurity risks if the benefits of connectivity are to be fully realised.

As more Nigerians embrace digital banking, e-commerce, cloud services and online communications, the consequences of compromised credentials or stolen personal information become increasingly significant.

The growing use of public Wi-Fi therefore highlights an emerging reality of Nigeria’s digital economy: internet access alone is not enough. Digital resilience increasingly depends on users understanding how cybercriminals exploit trusted technologies—and adopting safer online habits that protect their identities, finances and personal information.

For Nigerian internet users, the message from cybersecurity experts is clear. Free public Wi-Fi may save mobile data costs, but without appropriate precautions, it can also expose valuable personal information to invisible threats operating on the same network. As digital connectivity becomes more widespread, informed and security-conscious users will be better positioned to enjoy its benefits without becoming victims of cybercrime.
