Juice jacking is a type of cyber attack where data is stolen from the electronic devices via USB port when they are plugged in for charging. This has become so common that, Los Angeles' District Attorney's Office published an advisory to travelers about the potential dangers of public USB ports.
This works because data lines on the USB ports are not disabled during charging at the hardware level and often require the users to put their smartphones or other devices to charge only mode
. Fortunately there are devices like USB CONDOM
which disables the data lines during charging and prevents any form of data transfer
thereby preventing juice jacking.
But since Type-C USB devices use the data lines to negotiate voltage with the source; USB CONDOM would limit its function and thereby making the devices charge slower. This is counter intuitive as, we would want the devices to charge faster at a public charging point and there is a need gap.
