  • Wi-Fi is a popular computer technology that permits a mobile device to access the Internet over a wireless network connection.
  • Wi-Fi "hotspots" are commonly found in public areas such as airports, cafés, hotels, stores, gas stations, office buildings, schools, and libraries where visitors with a mobile device can get wireless access to the Internet via a Wi-Fi access point.
  • An "evil twin" is a term for a rogue Wi-Fi access point that appears to be a legitimate one offered on the premises, but actually has been set up by a hacker to eavesdrop on wireless communications among Internet surfers.
  • Hackers pose as legitimate Wi-Fi sources to steal passwords and other sensitive information from unsuspecting users.


  • Never surf the Internet on a Wi-Fi network without first enabling your firewall.
  • When possible, enable the Secure Sockets Layer (SSL) and HTTPS options to increase your security when accessing email and social networking sites.
  • Do not conduct transactions or exchange sensitive data on an HTTP web URL. Look for HTTPS sites which are safer and more secure.
  • Avoid exchanging sensitive data when using a public Wi-Fi network. Wait until you get home and have access to the Internet through a safe, trusted source.
  • Before connecting to a Wi-Fi network, be aware of the dangers of "evil twins".
  • Turn off the Wi-Fi connection on your mobile device when you are not using the Internet. Hackers can use it to create peer-to-peer Wi-Fi connections to your device, allowing direct access to everything on your device.
  • Enable wireless encryption and password protection when using Wi-Fi at home. You should be able to find instructions on how to do this properly in the documentation that came with your device or the online support site for your device. You may also find help on various how-to and tech-savvy websites.
