Every day, hundreds of thousands of us visit coffee shops. While we drink our coffee, we may connect our smartphone to the shop’s Wi-Fi network, and keep in touch with friends via services such as Facebook.
As well as socializing, we may use the time and free access to a wireless connection to get on top of our finances. Transferring money from your account to others’ accounts is nothing more than a few taps on your screen.
But what coffee drinkers do not realize is that lurking(潜伏) among their fellow coffee-lovers are bank robbers.
Unbeknown to you, this modern form of bank robber is silently collecting all your private data. The only sign of his thievery is perhaps a little smile as your bank log-in details appear on his screen.
You’ll only realize when you later go to a cash machine to withdraw(提取)some money, and discover that every penny in your account has been cleared out.
The common method for thieves is to use your smartphone’s Wi-Fi connection. They rely on the fact that most of us are not careful about the security of networks we connect to.
For example, when you are in a coffee shop, your smartphone will present you with a list of available Wi-Fi networks that you can use to connect your phone to the Internet. Most of these networks are run by legitimate(合法的)companies, but sometimes they are actually created by a thief sitting nearby with little more than a laptop.
These networks are often given names, such as “Free Public Wi-Fi”, which deceive smartphone users into logging in. On the surface, everything seems normal, and you will be able to connect just as you are with a legitimate Wi-Fi service.
However, because you have connected to a network controlled by a thief, he can monitor everything you do, enabling him to collect passwords and log-in details about your bank account.
