Public Wi-Fi Users Neglect Safety
A recent survey shows that 25% of Internet users have done online banking through public Wi-Fi in the last three months. It also shows that 27% have bought a product or service with a credit card this way.
Experts worry that hackers (黑客) will take advantage of these practices. Doug Shadel said that hackers usually attack in two ways. They may create Wi-Fi hotspots that have the same name of the ones you trust, such as a hotel or a coffee shop. They may also provide a stronger Wi-Fi signal to get between you and the safe hotspot. In either case, the hackers can see your email, credit card information, user names and passwords.
Sometimes hackers just set up their electronic traps near a business where people enjoy the free Wi-Fi. “In most cases they are after your personal information, Shadel said.“If you use the same user name and password for many accounts, they can get into them all. It's possible for any hacker to do it. The software to hack into a Wi-Fi network is available at little or no cost."
“It's difficult for people to know if a Wi-Fi network is safe," Shadel said. “So you should just think they are not. Any shared Internet access, free or paid, carries the same level of risk. It is safe only when you or someone you trust directly controls it."
Shadel sometimes checks email through public Wi-Fi. But he never does any banking that way. In an unfamiliar place, he uses a Virtual Private Network (VPN).“This service creates a passage between your device and a safe place on the Internet," he said.

【文章大意】公共Wi-Fi使用者忽视安全
最近的一项调查显示，在过去的三个月里，有25%的互联网用户通过公共Wi-Fi进行网上银行业务。调查还显示，27%的人用信用卡购买过产品或服务。
专家担心黑客会利用这些做法。道格·沙德尔表示，黑客通常通过两种方式进行攻击。他们可能会创建与你信任的Wi-Fi热点同名的Wi-Fi热点，比如酒店或咖啡店。它们还可以提供更强的Wi-Fi信号，将你和安全热点连接起来。无论哪种情况，黑客都能看到你的电子邮件、信用卡信息、用户名和密码。
有时黑客只是在人们享受免费Wi-Fi的企业附近设置电子陷阱。“在大多数情况下，他们想要的是你的个人信息，”沙德尔说。“如果你在多个账户上使用相同的用户名和密码，他们就能进入所有账户。任何黑客都有可能做到。侵入Wi-Fi网络的软件很便宜，甚至不用花钱。”
“人们很难知道Wi-Fi网络是否安全，”沙德尔说。“所以你应该认为他们不是。任何共享的互联网接入，无论是免费的还是付费的，都有同样程度的风险。只有当你或你信任的人直接控制它时，它才是安全的。”
沙德尔有时会通过公共Wi-Fi查看电子邮件。但他从来不那样做任何银行业务。在一个陌生的地方，他使用虚拟专用网(VPN)。“这项服务在你的设备和互联网上一个安全的地方之间建立了一条通道，”他说。
