Have you ever connected your device on public Wifi before? Let’s face it, public Wi-Fi is somewhat of a blessing. It keeps us in touch while on the go, but it is also public Wi-Fi, which can serve as a playing field for any hacker. This is something in which you are putting yourself in danger without knowing. Well, I am not saying you must never use it, but one does need to know the unseen dangers and protection methods.
In this article lets dive into the dangers of using a public wifi
Why Should You Care About Public Wi-Fi?
So the first question would be, why would using public Wi-Fi be such a bad thing? It really boils down to one issue: security-or rather, the complete and utter lack thereof. Publicly available Wi-Fi networks are not usually encrypted, which basically means it’s reasonably easy for a hacker to intercept something you send or receive.
Now, put yourself in a coffee shop environment, just seated and discussing one’s plans with someone over the weekend. But here, in place of having your conversations snooped on, they will actually be stealing your passwords, your credit card data, and even your identity. Yikes!
Why Using a Public Wifi is Wrong
Consider this: your Wi-Fi is password-protected, encrypted, and hopefully-behind a firewall at home. Here’s why using a public Wifi is terrible idea:
1. It’s ridiculously easy for hackers to intercept your data: Most public Wi-Fi networks are unencrypted, meaning whatever you send or receive can be sniffed up easily by any hacker. If you are logging into your banking app or entering sensitive details, someone’s watching.
2. Rogue Hot Spots Evil Twin Attack: Hackers create an open Wi-Fi network with deceptively recognizable names, such as “Free Café Wi-Fi” or “Airport_Internet.” The moment one connects to that, they successfully steal your information. Scary, right?
3. Distribution of Malware: Some of these can inject malware right into your device, and one wrong click might land spyware or ransomware on your phone or laptop.
4. Session Hijacking: Ever noticed how you remain logged into websites even after closing down your browser? That is because of something called session cookies. It is here that hackers hijack those cookies and access accounts-even when they don’t have your password.
How to Keep Yourself Safe on Public Wi-Fi?
Since we have viewed the risks, let’s dive into protection. You don’t need to stop using public Wi-Fi completely. You just have to be clever while using it.
1. Virtual Private Network – Your Best Friend
A VPN encrypts your internet traffic, and for hackers to get hold of your data, it becomes virtually impossible. It’s more like a secret tunnel that protects all your actions. Some decent ones include:
NordVPN
ExpressVPN
ProtonVPN
I know you are asking yourself if you needed to pay money for the VPN’S. Yes!! you will need to invest a few dollars in a nice VPN, but trust me, it is well worth it.
2. Don’t Access Sensitive Accounts
I know you might need to get into your bank account or pay something online while you are out and about, but if at all possible, wait until you are on a secure network. If urgent, go via your mobile data rather than public Wi-Fi.
Ask Yourself: Is this something I’d want a stranger to see? If the answer is no, maybe hold off.
3. Keep Your Software Up-to-Date
So the sincere truth is that hackers love taking advantage of unpatched software. Always keep applications, browsers, and the operating system updated in order to stay ahead of security threats.
4. Turn Off File Sharing
When you’re at home, file sharing is super handy. But on public Wi-Fi, it’s like leaving your front door wide open. Make sure to disable file sharing in your device’s settings.
How to Do It: On Windows: Go to Network and Sharing Center > Change Advanced Sharing Settings.
On Mac: open System Preferences, select Sharing, and uncheck everything.
5. Beware of Evil Twin Hotspots
Hackers simply love creating networks named something like “Free Wi-Fi” or “Airport Network.” So, first verify the name with the hotel staff before connecting. Red Flag: Any network that does not require a password to connect to is definitely insecure.
6. Forget the Network
After Use Forget the Public Wi-Fi Network when done, ensure your device has forgotten the public Wi-Fi network. It will help in avoiding cases of reconnecting automatically the next time and landing into vulnerabilities.
How to Do It: Go through your Wi-Fi settings either on your phone or laptop, locate the network, and tap “Forget.”
7. Trust Your Gut
If it feels wrong, like it’s asking too much from a website or some suspicious network, it probably is. Better safe than sorry.
8. Two-Factor Authentication (2FA)
If you enable Two-Factor Authentication, even if the hackers manages to get your password, they will not be able to login. If they try a one time code will be sent to your phone which will not give them the opportunity to hack your phone. Enable 2FA on these important accounts such as:
Email-Gmail, Outlook Social Media-Facebook, Instagram, Twitter Banking Apps
Benefits for Staying Safe on Public Wi-Fi
Now that you have learned how to protect yourself, let me outline why it will be worth it. Here are just some of the many advantages waiting for you once you make the decision to stay safe on public Wi-Fi:
Peace of Mind: You will be able to freely browse, shop, and even work with no worries of data compromise.
Protection against Identity Theft: Your personal details will be harder to access, and this will definitely translate into lesser chances of falling prey to identity theft.
