Everyone today seems to be constantly relying on their smartphones to help complete daily tasks which has resulted in the need to recharge subsequently increasing.
When you’re far from your charger, public charging kiosks can seem like a good substitute. However, this can lead to juice jacking of your smartphone. If this is news to you then let’s find out what juice jacking is and how you can avoid it.
The attack can be as simple as an invasion of privacy, wherein your phone pairs with a computer concealed within the charging kiosk and information such as private photos and contact information are transferred to a malicious device.
However, on the other hand, it can also be as invasive as an injection of malicious code directly into your phone. According to security researchers a smartphone can be compromised within one minute of being plugged into a harmful charger.
Exposure to a malicious kiosk can also create a lingering security problem even without the immediate injection of malicious code. Once a device is paired to a computer, it can access a host of personal information on the device, including your address book, notes, photos, music, sms database, typing cache, and even initiate a full backup of your phone, all of which can be accessed wirelessly at anytime.
How can one avoid this?
The most effective precautions center around simply not charging your phone using a third-party system.
Here are some tips to help you avoid using public kiosk charger
1. Keep your devices topped off
Make it a habit to charge your phone at your home and office when you’re not actively using it or are just sitting at your desk working.

2. Carry a personal charger
Chargers have become very small and portable, from USB cables to power banks. Get one and throw it in your bag so you can charge your phone anytime you’re at the office or while on-the-go if you use a power bank.

3. Lock your phone
When your phone is truly locked as in inaccessible without the input of a pin or equivalent pass-code, your phone should not be able to be paired with the device it’s connected to.

4. Power the phone down
This technique only works on phones on a model-by-model basis as some phones will, despite being powered down, still power on the entire USB circuit and allow access to the flash storage in the device.

5. Use power only USB cables
These cables are missing the two wires necessary for data transmission and have only the two wires for power transmission remaining. They will charge your device, but data transfer is made impossible.
