“When considering whether to connect to the public WiFi network at your local coffee shop, the airport, etc., I have two simple words of advice—don’t and DON’T. The massive flaw discovered in WPA2, the encryption standard that secures all modern WiFi networks, launched the possibility that anyone near you could easily access your information if you use a WiFi network. This includes information that was understood as being encrypted. Today’s WiFi standards are flawed and should not be trusted.
One of the biggest threats with free WiFi is the ability for hackers to position themselves between you and the connection point. So, instead of talking directly with the hotspot, you end up sending your information to the hacker. The hacker also has access to every piece of information you send out—emails, phone numbers, credit card information, business data, the list goes on. And once a hacker has that information, you’ve basically given them the keys to the kingdom.
However, despite numerous warnings, headlines, and efforts to educate, many people still don’t understand why connecting to free WiFi is an incredibly dangerous situation regardless of what you’re doing online. And while you may think ‘okay, I’m not checking my personal email or logging into my bank account, I’m just checking the sports scores,’ remember anything you do on a public WiFi network is NOT secure. Any information you share or access on these networks is as good as gone.”
