When you decide to plug your phone into a public USB port, it is like you decide to brush your teeth with a toothbrush you found on the side of the road… Exactly, you don’t know where it has been!
According to the Vice President of X-Force Threat Intelligence, Caleb Barlow, the public USB ports can install viruses into your phone and pass data as well, which is why you need to always keep your charger with you that can be plugged into a wall outlet.
Or even better, you can use a portable power bank that can charge your iPhone or Android anytime, anywhere!
In case you have no better option than using those USB ports, then Barlow suggest to buy a device called ‘Juice-Jack Defender’, it costs $10 and it is something you can put in front of the charging cord in order to pass only the voltage while blocking any data from passing to your phone.
As an average traveler, these precautions might look a little excessive, but it is smart to worry about those USB ports because according to IBM Security research, the majority of hackers are now focused on travelers.
In fact, the 2019 IBM X-Force Threat Intelligence Index found out that the transportation and traveling industry has become the 2nd most attacked industry by cybercriminals (it was 10th in 2017).
