If you connect your devices to anything public, be it wireless or wired Internet, or USB power charging stations, it is best to assume that these are not safe. While you can protect your data in several ways, e.g. by using a VPN when you need to access the Internet while connected to a public or untrusted network, it is sometimes the case that simple things are overlooked.
In November 2019, Los Angeles' District Attorney's Office published an advisory to travelers about the potential dangers of public USB ports. These ports could be used for an attack that has been called juice-jacking.
Juice Jacking basically allows attackers to steal data or infect devices that unsuspecting people plug into specifically prepared USB power stations. The Distrcit Attorney's Office recommended that travelers use AC power outlets directly, use portable chargers, or charge devices in cars instead of using public USB chargers.
While that is sound advice, it may not be possible sometimes to use these alternatives. That's where the Original USB Condom comes into play. The USB Condom is a device that is attached to the charging cable so that it sits between the device's charging cable and the public USB charging station.
The Original USB Condom prevents accidental data exchange when your device is plugged into a foreign computer or public charging station with a USB cable. The USB Condom achieves this by blocking the data pins in the USB cable and allowing only power to flow through.
The main idea behind the electronic device is that it blocks the data pins so that data cannot flow; this does not affect the charging capabilities so that devices may be charged as if they were connected directly to the charging station.
The device is available for $6.99 over at Syncstop. It is currently out of stock (as of early December 2019), but the site revealed that it expects the USB Condom to be restocked later this week.
The Original USB Condom is not the only device designed to block data transfers when connecting devices via USB to charging stations. A quick search returned PortaPow devices that block data transfers as well as others.
If you know someone who is traveling a lot, or spending lots of time in public places using public USB chargers at times, it may be a useful present.
