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.
