Huge flaw found in Wi-Fi security

- As baristas whip up lattes at Seven Grams Caffé in Chelsea, customers are taking advantage of the free Wi-Fi. But new research finds a Wi-Fi security flaw putting all of us at risk.

The WPA2 box, which encrypts traffic on Wi-Fi networks so hackers can't get in, isn't secure. That means your smartphones, computers, and routers could be hijacked.

"This isn't a setting that you can just change and you can fix for yourself -- this is a problem with the way people designed things," Scott Walsh of SecurityScorecard said. The senior threat intelligence researcher said hackers can now manipulate the security or inject new data that can steal your passwords, financial information.

All Wi-Fi, even at your home and free public (like Transit Wireless in subways), is at risk. Most of us log on and surf the internet while waiting for the train. But if you do, make sure the sites you visit begin with "https," which indicates those sites are protected.

Make sure your security software on your device is updated or ditch the Wi-Fi and stick to using your cell network or LTE data.
