By now we know that virus and malware infections are a real nuisance and more than that, sometimes a great threat to our privacy. But did you know that you can use USB condoms to protect yourself? As you read it, USB condoms could be "what the doctor prescribes" to avoid being attacked in insecure connections, and today we'll tell you how they work.
What are USB condoms
Quiet , that you will not have to go to the pharmacy for them nor will you have to wrap your mobile phone with a latex film. USB condoms refer to a very small and simple devices that have a USB connection that serves as a "bridge" between the connector you intend to use and your device, either the phone Smart, the tablet or any other you want to protect.
Neil Brown British expert in telecommunications, technology and online privacy, was the first to focus attention on these devices on his Twitter account in 2016, and each Once the need to use them day by day becomes more evident:

But when should you use USB condoms in your devices? The answer is: whenever you use a third-party device to charge your mobile .
Suppose you are in the airport waiting room and you notice that your mobile's battery is about to run out, and that your charger is in the suitcase that is already approaching in the baggage area. You will have no choice but to use a public USB charger.

With USB condoms you can charge your device anywhere because it allows the energy to pass, but does not allow devices to exchange data so that you will be free from malware viruses and will even protect the data from your mobile payments or your own identity.
How a USB condom works
A USB connection has four wires, two that serve for the power supply, and two more that serve to transmit data . So if you only want to receive energy, you will not need two of the charger cables, and this is precisely what USB condoms do: block two of the four connections.
And that is that by means of an unprotected USB connection, the cybercriminal s can easily get the data from your mobile. And do not think that because you are connecting your phone to someone's computer you will be free of viruses, because this type of infection is transmitted between devices.
For example, if a friend's computer has been infected with malware, and then he has used his USB cable to charge his mobile, the infection will travel through this connection . The next day you use your computer or even your USB charger to charge your phone, the infection has arrived.
The solution is simple: use the USB condoms that connect between the devices and the power supplies, and that with a very low cost (approximately 6 euros) you will be able to protect any device since they are universally compatible, and thus fill you with energy without worries.
And as if that were not enough, many of the USB condoms allow higher energy loads. So now you know, minimize the chances of stealing your data or installing malicious software on your mobile and connect safely and easily.
