9．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（潛伏） 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�。﹕ome 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．
