If you own any Apple device (iPhone, iPad, iPod, or a Mac computer) this is for you.
There is a security flaw in the way the Safari browser (the default browser on all Apple devices) handles secure websites. The security hole will allow a third party to intercept your communications with any secure website, whether you are logging into Gmail, Facebook, or your internet banking. The attacker merely has to be on the same network as you, meaning if you are connected to Wi-Fi at McDonalds and decide to login to internet banking, someone could potentially intercept your information and gain access to your accounts.
IOS version 7.0.6 has been released for all mobile devices, and you should apply this update immediately. If you own an iPhone 3GS, or older iPod touch, download update 6.1.6.
If you own a Mac computer which runs OSX, there is no patch released for this security vulnerability yet. The best way to protect yourself at this point is to download an alternate browser, such as Firefox or Google Chrome. Apple has indicated that they will be releasing a patch for OSX soon, but now that the flaw is receiving publicity, bad guys will be eager to exploit it, so you want to protect yourself the best that you can.
If you have a Mac computer at home and your Wi-Fi network is secure, you have nothing to worry about. If you’re using a MacBook and connect to public Wi-Fi at coffee shops, restaurants, libraries, etc., be sure to never access financial information, no online shopping, and no personal details.

To update your iPhone, go to Settings, General, Software Update and install every update available. If you haven’t update your phone in a while, you may have to install multiple updates. Updates are installed one at a time with the phone restarting after each one. When you reach update 7.0.6, that is the last available update. You should always keep the software on your phone updated to the latest version to protect yourself.
