iPhones can auto-connect to rogue Wi-Fi networks, researchers warn

iphone_pwSecurity researchers say they’ve uncovered a weakness in  iPhones that force users to connect to Wi-Fi networks that can then steal passwords or other sensitive information.

AT&T iPhones instruct the devices to automatically connect to a Wi-Fi network called attwifi when the signal becomes available, a service designed to speed up browsing.  But attackers can set up their own rogue Wi-Fi networks with the same name and collect sensitive data as it passes through.  AT&T are not the only company that are doing this, so don’t be smug if you have another carrier.

Researchers tested their hypothesis by setting up several Wi-Fi networks in public areas that used the same SSIDs as official carrier networks. During a presentation on Wednesday at the International Cyber Security Conference, the Skycure researchers set up a network that 448 people connected to during a two-and-a-half-hour period. 

The most effective way to prevent iPhones from connecting to networks without the user’s knowledge is to turn off Wi-Fi whenever it’s not needed. Apps are also available that give users control over what SSIDs an iPhone will and won’t connect to.

Staying Secure on Facebook

asset.f.logo.lgIf you have any concerns about security of the computer you’re using while accessing Facebook you can have them text you a one-time password to use instead of your regular password.  

Simply text “otp” to 32665 on your mobile phone (U.S. only), and you’ll immediately receive a password that can be used only once and expires in 20 minutes. In order to use this feature, you’ll need a mobile phone number in your account.

Of course if someone steals your phone and knows your email address (it’s in your phone address book right?) then this might be a simple way for them to get in – so hold on to that phone for dear life!
