The Dangers of Free Wi-Fi: Expert Advice to Stay Safe
Categories :
Public Wi-Fi is risky—hackers use fake networks, intercept data, and install malware. Unsecured connections expose personal information, leading to identity theft or financial loss. Avoid entering sensitive details, disable file sharing, and never click unknown links. A VPN encrypts data, ensuring privacy and security while browsing on public networks.
Public Wi-Fi may feel like a great convenience, allowing people to scroll, stream, and enjoy their coffee without using mobile data. But before connecting to every “Free_CoffeeShop” or “Airport_WiFi” network, it is important to think twice.
“Cybercriminals love public Wi-Fi even more than you do because they have many tricks to turn your browsing session into a digital disaster,” says Richard D, a cyber privacy expert at VPN Pro, a Virtual Private Network service that provides fast, secure, and unlimited internet access.
Below, Richard explains the dangers of public Wi-Fi and how to stay safe.
1. Fake Wi-Fi networks are everywhere
No, not the kind from TV dramas! Fake Wi-Fi networks, called ‘evil twins,’ are set up by hackers to trick people into connecting.
“These fake networks look like real ones, such as an airport’s official Wi-Fi,” says Richard. Unsuspecting users log in, thinking it is safe, but end up giving away their personal information without realising it.
Real-Life Story: In 2024, the Australian Federal Police arrested a man for setting up fake Wi-Fi networks on a plane. Passengers believed they were connecting to airline Wi-Fi but were handing over their emails and social media passwords to a cybercriminal—at 30,000 feet in the air!
Stay Safe: Always connect to verified Wi-Fi networks. If unsure, ask an employee for the correct network name. If a login page asks for personal details, like an email or password, think twice before proceeding.
2. Hackers can spy on your activity
When someone uses an unsecured public Wi-Fi network, hackers can intercept their data. This is known as a “man-in-the-middle” attack, where cybercriminals watch what a person is doing online—whether it is checking emails, logging into social media, or even entering payment details.
The scariest part? People have no idea it is happening. Hackers use special spyware tools to quietly capture personal information in real-time.
Stay Safe: “Never enter sensitive information (like banking details) while using public Wi-Fi. Stick to general browsing, and always assume someone might be watching,” advises Richard.
3. Unprotected Wi-Fi networks invite hackers
Most public Wi-Fi networks do not use encryption, meaning data is not protected. This makes it easy for hackers to steal personal messages, passwords, and account details.
If a cybercriminal gets access to an email and password, they can break into social media, banking, and other accounts.
Stay Safe: “Only use networks that require a password, as they are more likely to be encrypted,” says Richard. A safer option is to use a personal mobile hotspot so no one else can access the connection.
4. Clicking on the wrong link can install malware
Some hackers create fake pop-ups or apps on public networks. One wrong click, and malware is installed on a device. This malware can steal passwords, track activity, or lock important files.
Cybercriminals use public Wi-Fi to spread viruses, spyware, and keyloggers, which record everything a person types.
Stay Safe: “Never click on random pop-ups or download apps while using public Wi-Fi,” says Richard. “Keep security software updated and only install apps from trusted sources when using a secure connection.”
5. File sharing can expose personal data
Many people forget that their device’s file-sharing settings are turned on, which means anyone on the same public Wi-Fi can access their files. Hackers can use this weakness to steal personal documents, photos, and even install malware on a person’s device.
Stay Safe: “Turn off file sharing before connecting to public Wi-Fi and regularly check device settings to ensure no unauthorised connections have been made,” Richard recommends.
How a VPN can protect users on public Wi-Fi
Richard D, cyber privacy expert at VPN Pro, explains:
“A Virtual Private Network (VPN) is one of the best ways to stay safe on public Wi-Fi. A VPN encrypts all data, making it impossible for hackers to steal personal information. It works like a secure tunnel that keeps online activity private."
“Without a VPN, personal data is exposed to anyone with the right hacking tools. A good VPN also hides a user’s IP address and internet traffic, preventing cybercriminals from tracking them."
“Always use a trusted VPN when connecting to public Wi-Fi. It protects sensitive data and even helps bypass geo-blocks, so people can access their favourite content from anywhere in the world.”
