Your phone and tablet contain gigabytes of your personal information, which you probably don't want thieves, hackers or even snooping friends to get their hands on. That's why we strongly recommend setting up your gadget's lock screen and other security measures right away to keep everyone else out.
However, just because you've set up the security doesn't mean it's always foolproof. Occasionally, hackers and security researchers find flaws that could let someone trick their way in. There was a recent one in September, for example, that used Siri and some quick button pressing. Now, there's another one.
Discovery of the new flaw is courtesy of researcher Benjamin Kinz Mejri and Vulnerability Laboratory. It affects at the iPhone 5 and 6, and the iPad 2, running iOS versions 8 to 9.2. It might also work with other iPhones and iPads gadgets, but those weren't tested.
The bad news about this flaw is that Apple was notified about it in October and still hasn't released a fix, which leaves your gadgets vulnerable. It could be fixed in the upcoming iOS 9.3. The good news is that actually taking advantage of this flaw isn't going to be easy.
The flaw is in the iOS app update system. Done properly it creates an endless loop of the app pages on the home page. Once that's in progress, you can put the gadget into sleep mode using the power button and when it wakes up it doesn't ask for a passcode like it normally does.
To actually trigger this flaw, then, a snooper would need access to your phone while it was unlocked and some fancy timing. Or they would need to get you to install a modified app that could trigger the loop.
It's also possible that a hacker could figure out how to trigger a loop while the phone is still locked, but, again, they'd need access to your phone for a while. So it's a good reminder to keep your phone, and other gadgets containing sensitive information, in safe places.
