When traveling, you’ll eventually have to charge your devices in a public space, like a charging station at your airport gate. There’s a concept called Juice jacking where a hacker corrupts a USB port with malware that exports your personal data when you plug your phone in.

Still, it’s important to be aware of the risk, said Plam. Use your own power bank or the regular AC adapter instead of a USB port.
