Juice jacking is a security exploit in which an infected USB charging station is used to compromise connected devices³. The exploit takes advantage of the fact that a mobile device’s power supply passes over the same USB cable the connected device uses to sync data³. This can lead to data theft juice jacking attack or malware/virus infection juice jacking attack¹.
To avoid juice jacking, it's best to use your own charger and plug it into an electrical outlet instead of using public charging stations¹⁴⁵. You can also use a portable charger or a charging case for your phone¹.
