One thing that’s been fairly common throughout the many years iOS has been around is the promise of lock screen vulnerabilities — many versions of the operating system to date have fallen victim to tricks bypassing lock screen security. iOS 7 seemingly is no different, with YouTuber EverythingApplePro having discovered a method to gain access to iOS devices without proper authentication.
The bypass, which we’ve been unable to verify as working on our iPhone 5 (as that device is on the iOS 8 beta), is fairly simple to use, unlike others of years past. First of all, you’ll need to have a missed call, an app open in the foreground (behind the lock screen), and access to the Control Center from the lock screen.
Then, simply put the device in Airplane Mode, and tap on the missed call. You’ll immediately have access to whichever app was open in the foreground.
To avoid falling victim to this vulnerability, there are many things you can do. You can turn off Control Center access from the lock screen, make sure there are no apps running in the foreground before locking your device, or simply not have missed calls (the hardest of the bunch).
It’s safe to say Apple is working on a fix, and will release a patch release fairly soon to fix up the vulnerability.
