– Placing a cable in a public USB port is similar to finding a toothbrush on the road and stopping in your mouth. You have no idea where it was before.
The quote comes from Caleb Barlow, IBM Security chief, who says in an article in the Forbes business magazine, pointing to the risks of using a USB socket that is commonly found at airports.
Warns of fraudsters
Just as a criminal can read your credit card if he installed the equipment at the ATM, someone can do the same in the charging socket to get in the phone and now also warns the Norwegian Telenor.
"If you connect your mobile phone to an unknown USB connection, information on your phone can be retrieved. In addition, malicious code can be placed on your phone," Telenor writes in the Norwegian Dinside Warning.
One tip is instead to bring a "bank of power" – an extra battery for a mobile phone. Second, if you really want to be sure, get a USB condom that prevents data transfer to your mobile when it's charged.
Open network – risk
Warning also applies to reporting to open networks because you never know who is connected to it, and in the worst case you spy.
It is also not difficult for scammers to set up a wireless router and create a network with the same name as a serious operator, such as "Airport Wifi" for example. The hacker can then enter the phone to the person who reported and encountered sensitive codes, for example, warns Telenor.
