Essential cybersecurity tips for international travellers

Ah, the thrill of exploring a new country. Tasting exotic foods, navigating unfamiliar streets and immersing yourself in different cultures. Your passport is ready, your bags are packed and your smartphone is charged to capture every moment. But wait. Have you considered the cybersecurity risks that come with travelling abroad?

Just as you wouldn’t leave your hotel room unlocked, you shouldn’t leave your digital life unprotected, so let’s dive into how you can keep your devices and data secure while globetrotting.

Understanding cybersecurity risks when abroad

Unsecured public wi-fi networks

You’re sipping espresso at a charming café in Rome and decide to check your email using the free Wi-Fi. Seems harmless, right? Not quite. Many public Wi-Fi networks lack proper security measures, making it easy for cybercriminals to intercept your data and this could lead to problems ranging from identity theft to unauthorised access to your accounts.

Now, imagine you’re checking your bank account. While it may seem unlikely, a hacker nearby could use specialised software to eavesdrop on your connection, potentially capturing your login credentials as you access your account.

Data theft and device loss

Tourist hotspots can be magnets for pickpockets and opportunistic thieves. Losing your device isn’t just about the hardware, it’s about the treasure trove of personal and financial information it contains. And this could be a major issue particularly if your smartphone or tablet isn’t password-protected since a thief could access everything from your emails and photos to your payment apps.

Malicious charging stations (juice jacking)

After a day of adventure, your phone battery is dwindling. You spot a public USB charging station and plug in. Unbeknownst to you, this could be a trap.

More commonly referred to as juice jacking, this is a type of cyberattack that exploits the public USB charging stations found in places like airports, hotels, cafes and other travel hubs. When you plug your device into a compromised USB port or use a tampered charging cable, cybercriminals can gain unauthorised access to your device, which can result in two main types of threats:

• Data theft: your personal data, including contacts, photos, messages and even sensitive information can be extracted without your knowledge.
• Malware installation: malicious software can be installed on your device, allowing attackers to monitor your activity, steal information over time or gain control of your device remotely.

Phishing and social engineering in foreign languages

Navigating scams is challenging enough in your native language. Imagine receiving a phishing email or text in a language you’re not fluent in. The unfamiliarity can make it harder to spot red flags, increasing the risk of falling victim to scams. Think you’re not as gullible? Well, imagine receiving an official-looking email from your “hotel” asking you to confirm your credit card details due to a booking issue.

Pre-travel cybersecurity preparations

Update all devices and software

Before you jet off, ensure all your devices are up to date since software updates often include patches for security vulnerabilities. To check for updates, go to your device’s settings and look for any system updates. Also, make sure all apps are updated, especially those related to security, finance and communication.

Back up important data

This includes items like your photos, contacts and important documents to a secure cloud service or external hard drive. This way, even if your device takes an unscheduled trip without you, your data remains safe. Consider using cloud services like Google Drive, iCloud or Dropbox, or make use of physical backup, such as an encrypted external drive.

Install reliable security software

Equip your devices with trusted antivirus and anti-malware applications. The first step to doing so is to research reputable apps, then make sure the software actively monitors for threats in real-time.

Set up device tracking and remote wiping

Enable features like “Find My iPhone” or “Find My Device” on Android. These tools allow you to locate your device or erase its data remotely if it goes missing. Also, don’t forget to turn on location services for device tracking apps and of course, make sure you familiarise yourself with how to use remote lock or wipe functions.

Review privacy and security settings

Adjust app permissions and disable unnecessary services like Bluetooth and NFC when not in use since every open connection is a potential door for cyber intruders. In addition, remember to revoke access for apps that don’t need location, microphone or camera.

Safe connectivity practices while abroad

Use a Virtual Private Network (VPN)

A VPN encrypts your internet connection, making it harder for anyone to snoop on your online activities. It’s like having a private tunnel through the chaotic traffic of the internet. But before downloading whatever VPN comes your way, choose a reputable option and make sure to set it to auto-connect so that it activates whenever you’re online. Take a look at this comprehensive guide explaining everything there is to know about VPNs.

Opt for data over public Wi-Fi

As mentioned above, public Wi-Fi spots may be convenient but may hide all sorts of threats. Whenever you can, use mobile data since mobile networks are generally more secure than public Wi-Fi.

Once you’re all set with your mobile plan and are enjoying your travels, you can then use your smartphone as a personal hotspot by creating a secure connection for your other devices.

Disable automatic Wi-Fi connections

Your device might be too friendly, automatically connecting to any available Wi-Fi. Consider turning off this feature to prevent unwittingly joining a malicious network. Doing so is super simple, just go to your wi-fi settings and disable where it says ‘Connect to open networks automatically’.

Be cautious with Bluetooth connections

Your Bluetooth can be another avenue for cyberattacks. Remember when your phone tried to pair with ‘Unknown Device’? Let’s avoid that. Keep it disabled when not actively using it and it’s best if you remove old or unused Bluetooth connections altogether.

Secure use of devices

Practice safe browsing and email habits

Just because you’re on holidays that doesn’t mean you should let your guard down. Which means that while that email titled ‘You’ve Won a Free Cruise!’ might be tempting, it’s best to be skeptical. And of course, avoid clicking on suspicious links or downloading attachments from unknown sources. Also, consider using browsers with built-in security features like Chrome or Firefox.

Enable Two-Factor Authentication (2FA)

2FA adds an extra layer of security by requiring a second form of verification. It’s like having a double lock on your digital door. If you’re wondering where you should activate this feature, consider doing so on accounts like your email, social media and, of course, banking.

Limit use of sensitive transactions

Avoid accessing your bank account or making online purchases on public networks. Ideally, handle any essential transactions before your trip and if you really must use these, ensure you’re using a VPN and that you’re on official apps with encryption rather than web browsers.

Be wary of public charging stations

Remember the juice jacking we talked about? Charge your devices using your own charger plugged into an electrical outlet or carry a portable battery pack, which can be a lifesaver when outlets are scarce. Alternatively, if you really do need to make use of public charging stations, use a USB data blocker – a device that prevents data transfer while charging.

Physical security measures

Keep services secure

As you stroll down an idyllic Parisian alleyway, you decide it’s the perfect moment to take a picture. But as you reach into your back pocket, horror strikes – you realise your phone is missing. Is it in your backpack or did you leave it somewhere? Always keep track of your devices and never leave them unattended on tables or in unlocked hotel rooms. It’s the digital equivalent of leaving your wallet on the dashboard.

On the other hand, when you don’t need your device, secure it in your hotel room’s safe, otherwise, when you’re out and about, opt for secure or anti-theft bags with hidden zippers and locks to keep your belongings protected.

Use strong passwords and biometric locks

Ditch “1234” or “password” as your unlock code and instead create a complex password which combines letters, numbers and symbols. And to be even safer, activate fingerprint or facial ID features.

Be mindful of your surroundings

Avoid using your devices in crowded areas where thieves might be lurking and even better, avoid flashing expensive gadgets in public. Plus, who wants to be that tourist glued to their phone instead of soaking in the sights?

Post-travel cybersecurity actions

Change Important Passwords

Once you’re back home, you should update your passwords. At the very least, do so for those of key accounts like email, banking and social media. Another option to make this task less daunting is to use a password manager. Not sure what that is? Read all about it here.

Review account activity

It would be a good idea if you review your accounts over the next few weeks and look out for any unusual activity. Early detection is key to resolving issues quickly.

Run security scans on all devices

Perform thorough scans using your security software to detect any hidden nasties that might have hitched a ride home. Of course, before doing so, ensure your antivirus is current before scanning and scan all your devices.

Travelling the world is an enriching experience and with a bit of preparation, you can ensure your digital life remains as vibrant as your journey. Simply follow the tips above so that you’re not just protecting your devices, but you’re ensuring your adventures are memorable for all the right reasons.
