You’re rushing through the airport, phone battery at 8%, and there’s a convenient USB port right at your seat. But federal authorities are warning that plugging in your device could expose your financial accounts to hackers.
Both the Transportation Security Administration and Federal Communications Commission have issued alerts about “juice jacking,” a practice where cybercriminals install malware through public USB ports to steal personal data.
It’s one of several digital threats that you face while traveling.
The FCC recommends travelers stick to traditional AC power outlets instead. If you must use a USB port and your device prompts you to “share data” or “trust this computer,” always select “charge only.”
Better yet, pack a portable power bank (in your carry-on) or use your own AC adapter.
For older travelers who might be less familiar with newer threats, the risks are particularly high. They may not recognize warning signs of a compromised device until significant damage is done.
Beware free Wi-Fi too
Free airport internet can also be a goldmine for criminals hunting for financial information. TSA warns against making online purchases or entering sensitive data while using unsecured public networks.
Security experts agree that it’s wise to be especially cautious when entering passwords on public networks.
One recommendation is to invest in a virtual private network service, which encrypts your internet connection and adds a layer of security between your device and potential hackers.
Password managers offer yet another layer of protection by encrypting and storing passwords securely.
Instead of constantly checking your accounts throughout your trip, designate specific times and secure locations for financial tasks. Your hotel room’s secured Wi-Fi — along with your VPN — beats the free Wi-Fi in airport lounge every time.
For urgent financial tasks, use your phone’s cellular data rather than public Wi-Fi.
Simplify your spending while traveling
Consider using a dedicated travel credit card with a lower limit for trip purchases. This minimizes potential damage if the information gets compromised and simplifies monitoring for fraud.
Many cards now offer virtual numbers for online purchases, adding extra protection.
Pro tip: It’s easy to find a credit card that suits your travel needs at comparison sites like this one.
