Have you ever plugged your phone into a strange USB port because you really needed a charge and thought: "Gee who could be stealing my data?". We all have needs and sometimes you just need to charge your phone. "Any port in a storm" as the saying goes.
Well now you can be a bit safer. "USB Condoms" prevent accidental data exchange when your device is plugged in to another device with a USB cable. USB Condoms achieve this by cutting off the data pins in the USB cable and allowing only the power pins to connect through.Thus, these "USB Condoms" prevent attacks like "juice jacking".
