Another Lock Screen Bypass Flaw Found in Apple's Latest Apple iOS Software (Video)

Just two days after Apple announced that it had fixed a lock screen bypass flaw in its latest iOS software, another lock screen bypass bug has been discovered.

It took Apple 34 days to fix a lock screen bypass flaw that was reported on its new iOS software. Apple recently upgraded its iOS system to iOS 6.1.3. The update weight is 18.2 MB and can be downloaded directly to an iOS device from the Settings/General/Software Update menu or through iTunes.

Hours after the new upgraded version was released, a flaw with iPhone and iPad lock screens that allowed hackers to easily break into a user's iOS 6.1-powered device was discovered. Just two days after that was fixed, a new lock screen bypass flaw has been found.

YouTube user videosdebarraquito posted a video where he showed people how he was able to bypass the lock screen on an iPhone 4 using nothing more than a paperclip. If the device is locked but the voice control feature is enabled, it is easy to bypass the lock screen. All one needs to do it eject the SIM card from its tray the moment the device starts dialing.

By doing this, the phone's application remains open and people can access recent call logs and contacts of the phone. Voicemail is also accessible if it is not protected by a separate PIN code.

Photos from the phone's gallery can also be viewed by creating a new contact which then automatically opens up the phone's photo gallery and other photo applications including Camera Roll and Photo Stream.

However, if the screen turns off, the phone automatically locks again but can be opened with the eject SIM trick several times.

According to a report by ZDNet, this happens because as soon as voice control is used, the phone automatically begins to load its applications in the background. As the call begins, for less than a second the phone application displays as it transitions away, and is immediately replaced by the lock screen once the call ends. When the SIM card is removed, the transition is stalled and the phone is kept in active play as the action "confuses" the device.

An immediate solution to this bug has been recommended by disabling voice control. This can be done by going to Settings, click the General tab, then Passcode Lock. From here, disable Voice Dial on older versions of iPhones, or enable Siri for an iPhone 4S or older.
