Imagine that you’ve just landed in a new city, ready to start your vacation that you’ve been looking forward to for months. You are jet-lagged, your SIM card isn’t working, and that sweet “Free Airport Wi-Fi” sign is beginning to look pretty good. But before you click Connect, here’s a reality check: Public Wi-Fi is still one of the biggest cybersecurity risks for travelers. Hackers LOVE public Wi-Fi – these days, cybercriminals use fake hotspots, man-in-the-middle attacks, and even AI-powered sniffers to steal your data while you sip your espresso. So, what should you do? Let’s look at the dangers of public Wi-Fi while traveling and how to stay safe without giving up convenience.
The most common Wi-Fi traps
Public or free Wi-Fi can be more dangerous than it seems. Let’s look at a few of the most common traps.
1. Fake hotspots
Hackers can create “evil twin” networks by creating their own hotspot with a similar name to the legitimate Wi-Fi. Think of names like:
- Airport_WiFi_Free
- Cafe_GuestNetwork
- Hotel_WiFi123
These may look legit but are designed to intercept everything you send like passwords, credit card info, and even your work emails.
2. No encryption
Many public Wi-Fi networks don’t use encryption which is used to make your data unreadable, which means that anyone nearby can eavesdrop on what you’re doing. These Wi-Fi networks don’t have a lock icon which shows that it isn’t encrypted.
3. Session hijacking
Attackers can hijack or takeover your session and pretend to be you by stealing your cookies. This is a type of man-in-the-middle attack. They can steal your login cookies from an active session and then access your accounts.
4. Malware injection
Hackers can inject malware directly into your device if it’s not protected. Think of outdated software, pop-ups, or using one of the techniques mentioned previously. And you know how dangerous malware can be…
Risky travel Wi-Fi examples
Here are a few examples that you can look out for when you’re travelling:
- Airports. Airports are easy targets because you’re stressed and tired from your flight, you’re desperately looking for connectivity, and you just want to get to your hotel. In addition, there are so many people feeling the same way which is perfect for cybercriminals to launch their attacks.
- Hotels. It’s easy to assume that whatever Wi-Fi is available in the hotel is legitimate, but that’s not necessarily the case.
- Cafés and restaurants. Their focus is usually on customer service, not cybersecurity, and they often have the weakest security measures. Also, because of their location, it’s easy for hackers to set up fake networks.
- Public transport. While this isn’t available everywhere, Wi-Fi on trains, buses, and ride-shares can make it hard to verify if it’s legit because of the constant movement.
But it’s not all doom and gloom. Let’s look at how we can stay safe.
7 ways to stay safe on public Wi-Fi
Now that we’ve scared you (just a little), let’s talk about what you can do to stay safe when using public Wi-Fi.
1. Use a VPN
A VPN (Virtual Private Network) encrypts your connection, even on dodgy networks. It scrambles your data, making it unreadable to anyone else. Use a VPN each time you connect to help keep your data away from prying eyes.
Pro Tip: Turn on “Auto-Connect VPN” in your phone/laptop settings.
2. Turn off auto-connect
Turning off auto-connect prevents your device from automatically connecting to a rogue network. This allows you to choose the network that you want to connect to instead.
How to turn it off:
- iOS: Settings > Wi-Fi > Auto-Join = Off
- Android: Settings > Network > Wi-Fi Preferences
- Laptops: Uncheck “Connect Automatically”
3. Ask the staff
Don’t assume the Wi-Fi name. Just ask the staff to be sure that you’re connecting to the correct one. Remember that the staff are there to help you, so just do it.
4. Avoid accessing your sensitive accounts
Try to avoid logging on to online banking, emails, cloud drives, etc. when using public Wi-Fi. If you really need to do it, use your phone’s data or a VPN to secure your traffic.
5. Stick to HTTPS
Only visit websites that use HTTPS or has a padlock next to the name in the address bar. If the website doesn’t use HTTPS, don’t enter ANY personal info.
6. Update your software
Ensure that all your software is updated and use an antivirus. A vulnerable app is an easy way for a hacker to access your device. Turn on automatic updates so you don’t forget.
7. Log out & forget the network
When you’re done, ensure that you log out of your account and click “Forget Network” so that you don’t accidently reconnect later. Close any apps that you were using and clear your browser cache.
Bonus tip: Use your phone as a hotspot
If you have an international SIM or eSIM, you have the option to use your phone as a hotspot. This is probably one of the safest methods you can use and eliminates the need for public Wi-Fi.
The cyber-savvy traveler’s public Wi-Fi checklist
Use this checklist to help you stay safe when using public Wi-Fi.
1. Before connecting:
- Verify the network name with staff
- Turn on your VPN
- Disable auto-connect features
- Turn off file sharing and AirDrop
2. While connected:
- Stick to HTTPS websites only
- Avoid online banking and shopping
- Keep sensitive apps closed
- Monitor your device for unusual activity
3. After disconnecting:
- Forget the network
- Clear browser cache and cookies
- Run a security scan on your device
- Check for unauthorized account access
Bonus!
Here is a short tip guide for the solution based on the risk:
- Fake Wi-Fi names = Ask staff + VPN
- Data sniffing = Use VPN + HTTPS
- Device hacks = Update software + use antivirus
- Session hijacking = Log out + don’t auto-connect
- Password theft = Use strong passwords + 2FA
Final boarding call!
Public Wi-Fi is convenient, but it’s also one of the easiest ways to get hacked while traveling. The good news is that staying safe isn’t that hard. So, follow our tips to ensure a risk-free vacation. Let us know if you’ve ever connected to dodgy Wi-Fi and tag us on social.
