How many times have you plugged your phone into a public outfit or charging station? Just by plugging your phone into a compromised power strip or charger, all of your data can be hacked.
"Juice jacking" is a real term and it's described as a compromised port that allows a hacker to access your text messages, photos, contacts, and email.
Since there's no way to tell whether or not a public outlet or charging station has been compromised, you should avoid plugging your phone into one in the future.
Here are a few more tips to help protect your phone:
Leave home with a charged phone.
Buy a portable USB battery pack.
Invest in a USB cord that doesn't transmit data.
Make sure your phone is locked with a PIN or a password.
