A vacation abroad. You can finally relax, enjoy the local food, walk through the old town and park your car by the hotel or a popular tourist attraction. But while you are admiring the view, someone else may be watching you – or, more precisely, your devices.
In popular tourist destinations – from the Croatian coast and sun-drenched Spanish beaches to French resorts – increasingly sophisticated thieves and cybercriminals are targeting tourists. This is not about someone stealing from your bag in a crowd. It is about silent, invisible threats that most people do not even know exist.
Here are seven things your phone and other devices can reveal while you are on vacation, along with what you can do about them.
1. Your Car Is Unlocked – Even Though the Key Is in Your Pocket
If you have a modern car with keyless entry, you may have a problem. The system works by continuously transmitting a signal and looking for the key nearby. However, this signal can be intercepted and amplified.
Thieves in tourist areas commonly work in pairs. One stands close to you – near a lift, in a restaurant or in a car park – while the other waits by your vehicle. A special device relays the signal from your key to the car, causing it to unlock as if you were standing directly beside it. The entire process takes only seconds. It is known as a relay attack and is the fastest-growing method of vehicle theft in Europe.
What to do: Keep your car key inside a Faraday bag, a special RFID-protected pouch that blocks wireless signals. Faraday bags act as an electromagnetic shield: the key inside can neither receive nor transmit. No signal, no theft.
2. Your Payment Card Can Pay – Even When You Do Not Take It Out
Contactless payment cards are convenient. You tap and pay. But someone else may be able to “tap” just as easily without you knowing.
RFID skimmers are devices capable of reading data from contactless cards. They are now small enough to fit inside a pocket. An attacker can pass close to you in a crowd, queue or on public transport and capture your card data in a fraction of a second. In heavily visited tourist locations, this is not an exception but a common practice.
What to do: Carry your card and other documents in a Faraday bag or use an anti-skimming blocking card. It follows the same principle as the protection for your car key. No signal, no reading.
3. Your Passport Contains a Chip – and It Can Be Read Remotely
Modern biometric passports contain an RFID chip holding personal information such as your name, date of birth, photograph and passport number. Under certain conditions, this chip can be read wirelessly without opening the passport.
In crowded tourist areas, airports or queues for attractions, this represents a real risk. Passport data can be misused for identity theft, opening fraudulent accounts or committing other scams.
What to do: Carry your passport inside a Faraday bag together with your cards and other documents. Present it only when genuinely necessary, and never leave it loose inside a backpack or bag.
4. Hotel Wi-Fi Is an Open Book
“Hotel_Guest_Free” – this is what Wi-Fi networks in hotels, cafés and tourist centres often look like. They are convenient, free and very dangerous.
On unencrypted or poorly secured networks, an attacker may intercept all your communication, including passwords, emails and online banking credentials. The technique is known as a man-in-the-middle attack, and for an experienced attacker it is a routine operation.
What to do: Use a VPN, or Virtual Private Network, to encrypt your connection. Do not access online banking or send sensitive documents over unfamiliar networks. Prefer mobile data to unknown Wi-Fi.
5. Bluetooth Broadcasts Your Location – Even When Nothing Is Connected
Is Bluetooth switched on? If so, your phone continuously broadcasts an identifying signal to its surroundings. This signal can be detected and used to follow your movements: when you arrived, which way you went and where you spent time.
In tourist destinations, this is used both by commercial organisations – shopping centres tracking customer movement – and by more sophisticated thieves mapping tourists’ habits. They may observe when you leave your car, how long you remain away and whether you have returned.
What to do: Carry your phone in a Faraday bag or manually switch off Bluetooth whenever you are not actively using it. A phone inside a Faraday bag is essentially in the same state as a phone with Bluetooth disabled. No signal goes out and no signal comes in.
6. A Public Charger Can Be a Trap
Airports, cafés and hotels often provide USB charging ports. Practical? Yes. Safe? Not always.
A technique known as juice jacking involves an attacker installing malware through a public charging station. When you connect your phone, the malware can be transferred to the device, potentially providing access to your data, photographs, contacts or login credentials.
What to do: Carry your own wall charger. If you must use a public USB port, use a data blocker, sometimes called a USB condom. This small adapter allows electrical power through while blocking data transfer.
7. Your Phone’s GPS Records Every Step
A photograph from your trip may contain the exact GPS coordinates of where it was taken in its metadata. Are you sharing vacation photos on social media in real time? You are revealing where you are – and, more importantly, where you are not. This may indicate that your vehicle or hotel room is unattended.
Thieves in tourist areas now actively monitor social media. A photograph captioned “We’re finally at the beach!” may tell them that your car is parked some distance away and that you will be gone for at least three hours.
What to do: Share your vacation photographs only after returning home, or at least after a delay. Check your phone’s location settings and restrict unnecessary application access to GPS.
Conclusion: A Vacation Should Be Worry-Free – Not Unprotected
None of these tips requires technical knowledge or a major investment. They involve simple habits and a few small tools that can significantly reduce the risk of your vacation turning into an unpleasant experience.
Car keys, payment cards and a passport inside a Faraday bag, Bluetooth switched off, a VPN on hotel Wi-Fi and your own charger: that is the complete security kit for a traveller who does not want to be an easy target.
Popular tourist destinations are not only home to pickpockets. They also attract people who know exactly what they are doing – and count on you not knowing.
