JakartaHerald.com - As more Indonesians travel abroad for work, study, or leisure, digital security has become just as important as keeping your passport safe.
In an age where everything — from flight bookings to hotel check-ins — is handled online, your digital identity is constantly at risk.
Cybercriminals are increasingly targeting travelers through unsecured Wi-Fi, fake travel apps, and phishing scams.
Understanding how to protect your personal data while traveling is now essential.
Here’s what every Indonesian traveler should know about digital security in 2025 and 2026
1. Public Wi-Fi: A Hidden Threat
Free Wi-Fi is a lifesaver at airports, cafés, and hotels, but it’s also one of the most common traps for hackers.
When you connect to a public network, cybercriminals can intercept your data — including passwords, messages, and even bank details.
How to stay safe:
- Always use a VPN (Virtual Private Network) when browsing on public Wi-Fi.
- Avoid logging into financial apps or email accounts while on unsecured networks.
- Disable automatic Wi-Fi connections on your phone or laptop.
- Using a VPN encrypts your internet traffic, making it nearly impossible for hackers to read your data even if you’re connected to the same network.
2. Beware of Fake Apps and QR Code Scams
Scammers often create fake versions of popular travel apps like hotel booking platforms or navigation tools. These apps may look legitimate but are designed to steal personal information or install spyware.
Similarly, fake QR codes — now common in restaurants and tourist sites — can redirect you to phishing pages or malware downloads.
Tips to avoid this:
- Download apps only from official stores (Google Play, App Store).
- Double-check the app developer’s name and user reviews.
- Avoid scanning random QR codes unless you trust the source.
- If you’re unsure, manually type the URL instead of scanning.
3. Protecting Your Devices While Traveling
Losing your phone or laptop abroad can be devastating, especially when they store your personal and financial data.
Before you travel, make sure to secure your devices properly.
Best practices:
- Set up biometric locks (fingerprint or face ID) and strong PIN codes.
- Enable “Find My Device” or “Find My iPhone” to locate lost gadgets.
- Back up your important files to a secure cloud service.
- Additionally, avoid leaving devices unattended — even for a few minutes — in public areas such as cafés, airports, or train stations.
4. Using Digital Payments Safely Abroad
E-wallets like GoPay, DANA, and OVO have made payments easier for Indonesian travelers, but using them abroad requires extra caution.
Always make sure that:
- Your e-wallet is connected to a verified account.
- You enable two-factor authentication (2FA) for transactions.
- You log out after each session, especially on shared devices.
- When using credit cards or ATMs, choose reputable machines in secure locations — preferably inside banks or airports — to avoid card skimming.
5. Social Media and Privacy Awareness
Many travelers love sharing their experiences online, but oversharing can expose you to risks like theft or cyberstalking. Posting real-time locations or travel plans publicly allows criminals to track your movements.
Smart sharing tips:
- Wait until after leaving a location before posting photos.
- Keep your social media accounts private while traveling.
- Avoid posting boarding passes or hotel details online.
- Remember, digital footprints can last forever — so think before you share.
Final Thoughts
Digital security for travelers is no longer optional — it’s a necessity. Whether you’re a student studying abroad, a freelancer working remotely, or a tourist exploring a new city, protecting your data is as important as keeping your passport safe.
By following basic cybersecurity practices — such as using VPNs, securing devices, and being cautious with online transactions — you can travel confidently without worrying about digital threats.
In today’s hyper-connected world, staying digitally safe means staying one step ahead of the hackers.
