Charging in public spaces? Be wary of "juice jacking".


Charge your laptop or phone at airports, hotels, cafes or even shopping centres.

The FBI issued a warning about using USB charging ports, as criminals use these to spread malware and spy software while their devices charge.

Long considered an abstract threat, "juice-jacking" has now become more mainstream. With technology becoming smaller and easier to use than ever before, juice-jacking has been taken advantage of by less sophisticated criminals to launch attacks against consumers and enterprises alike.

How Does Charging Work Precisely? Most USB-C and Lightning charging cables serve dual purposes - using their pins both for charging and data transmission.

Your device only charges using its pins; however, an improper charging port or cable could allow someone else to take advantage of both data and charging pins for data transmission and charging purposes.

Criminals can use data pins to install malware on your device and gain access to your credentials and data - much like plugging your phone into someone else's computer.

Avoid this risk by carrying your charger and cable with you and plugging them directly into an outlet. If necessary, purchase a USB data blocking device so your device can still charge while data cannot be transmitted between ports.
